Unraid zfs compression. I've been testing unraid 6.

Unraid zfs compression With my datasets (there are quite a lot). Although I am ambivalent about compression on already compressed files like h264 and the even more compressed Hi thanks for starting this wonderful plugin. 14-1 root@UNRAID:~# zfs version zfs-2. Not sure what the problem could be, but you could try send/receive that snapshot to a new dataset and the then run the container on that dataset, e. What is the best way to move these files onto the drives to begin with? This method will retain all ZFS-specific features, including datasets, snapshots, compression, permissions, ACLs, and hard links. 2) and the problem still perstists, but as i already pointed out, the problem only occurs, when the docker. Allow me to change the ZFS compression instead of lz4 to zstd as it resets everytime the array stops Keep the good - created a notepad doc with this: options zfs zfs_arc_max=32000000000 - saved it as zfs. Then also converted virtual machine folders into datasets. The Update Assistant reports no issues and the upgrade appears to go smoothly, except for the import of my ZFS pool. alexander; July 27; SMB Slow Directory Listing ZFS + Time Machine - Hints (SLOG) By scot, March 19. Most users already on Unraid will probably be happy with the status quo, but ZFS on Unraid will appeal to a lot of new users that liked all the other aspects of Unraid, but were put off by lack of ZFS. 12 from 6. This video prompted that. I have turbo write enabled, and in the Disk Settings, I have it set to reconstruct write. Ich habe bei meinem Test unRaid Server nun 4 HDDs zum ZFS RaidZ1 via Konsole fertig gemacht jedoch kann ich Standard Funktionen virtuals compression lz4 local virtuals atime off local Or one of each unraid / zfs (that's what I'm going to do). Help I already have a zfs cache pool up and running but forgot to turn on compression. However, with the ~1% compression ratio from earlier, I'd expect to see either 0. Tried to format to ZFS - encrypted -> didnt work. -> didn't work aswell. If you go unRAID, putting down quite a lot of money, you do it for the array. formatted as ZFS compression on lz4 named vm_drive (2TB Nvme). 04 (and some derivatives like Zorin), Proxmox and TrueNAS ship with ZFS by default and Unraid has a plugin that adds ZFS capability. Yes, LUKS does support TRIM as well, but it's disabled by default and it has security implications due to free space not being encrypted, defeating one of the advantages of FDE over ZFS's native encryption. 0-rc. 12 is compress=zstd. It was for a prototype of a backup-to-disk-to-tape server. Go to unRAID r/unRAID. VM Manager Improvements.

Finally getting round to re-upgrading to 6. The rest pools are displayed correc Light Mode Dark Mode. 6 With Unraid settings as a ZFS pool you can only export the root pool, it doesn't do any of the datasets Which makes sense why I can see all the folders when I mount the NFS drive that way but can't see any files So I would need an option in Unraid to be able to mount all the datasets as well The way I do it with the script now works because the Process to use ZFS in Unraid (Thanks to Wendell from Level1 techs for the baseline) Unraid needs to be running with at least 1 data drive, pref 1 parity and 1 data drive. Is it ok to turn off the array, turn on compression and turn it back on with data in it? Just making sure it won't wipe out anything or cause any issues! Compression. Developed by Lime Technology, unraid offers a unique approach to storage by utilizing a combination of traditional RAID and JBOD (Just a Bunch Of Disks) configurations. Unraid 7. It will be more efficient than copying files with dd The official suggestion from @MAM59 is that the unraid array should NOT be ZFS and should remain as XFS (or BTRFS if you're brave) I will begin the arduous process or converting all my array disks back to XFS. 12 release: You will be able to select zfs as file system type for single unRAID array data disks. Probably a silly question, as ZFS is ZFS, but is there any negative impact to the usage of this plugin or ZFS features, considering they are not exposed in Unraid itself nativly? For example, if i create sub-datasets and/or snapshots, then Unraid 6. So it should look like this if your pool name is called “cache” zpool trim cache Reply reply Top 2% Rank by size . Ich habe die Option "Compression" aktiviert und der Speicherverbrauch ist von 720GB auf 495GB (ca. Also have 4 x 200G SSDs (Oracle F80 PCIe card) acting as my zfs cache. That means 7 years of rock solid and problem free up time. It is possible that Unraid has put this into the GUI itself and runs these commands in the background. root@Tower:~# zpool upgrade SSDThis system supports ZFS pool feature flags. 39x or 4. Autotrim can be configured as on or off (except for single-device ZFS volumes in the unRAID array). Only one row which has SHOW DATASETS, SCRUB POOL, EXPORT POOL and CREATE DATASET is showing. 9. There are more unraid zfs features to come down the line that will benefit the main array. ADMIN MOD ZFS Compression . With ssh/scp transfers you can enable compression, that So der Umzug auf ZFS hat funktioniert, Docker und VM laufen. Able to have Primary Storage as Cache drive and Secondary storage as a Pool (zfs) 2. Yeah, but zfs with compression with this data is faster that zfs/btrs without compression, these were the results of the same test with zfs: Compression. Making the switch is worth considering, and this guide focuses on helping you reformat I know ZFS allows compression which could be useful for uncompressed ISOs, assuming you have the CPU overhead to handle the compression algorithms (13700k here). Hi guys, a new minor-update is live with the following changelog: 2022. I haven’t used the unraid array for many years now so that’s not an issue. Quote Sanoid is a policy-driven snapshot management tool for ZFS filesystems. 7T 0 part └─sdh9 8:121 0 8M 0 part I start with it not mounted after a reboot: zpool status no pools available But I am struggling to import, f ZFS in unraid ändert an der Philosophie dahinter nix. having an expand / retract feature. what happens to my array if one of the drives filles up to maybe 50GB free space? i know performance is going to tank hard on the way there but will it render the filesystem (or array) unusable? since this never happened to me before i could use some input. 0. Which I personally only care about the compression and encryption. You will be able to select zfs as the file system for a pool. Disabling ZFS compression is quite easy: root@server:~ # zfs set compression=off newvol ZFS Compression Works Only for Future Data. In both the Traditional ZFS (pure Zpool) and Hybrid Approach scenarios above, I have highlighted compression and snapshots as advantages for the ZFS dataset where you store media files. 7T 0 disk ├─sdh1 8:113 0 12. Sure, as a single device lots of zfs redundancy features don't exist, but it can be a target for "zfs receive", and it can utilize compression and snapshots. Unraid's recent addition of ZFS support opens up new possibilities for data management and having an array drive as ZFS opens up alot of possibilities such as zfs replication between two zpools. zdb -C tank | grep ashift ashift: 12 zfs get compression NAME PROPERTY VALUE SOURCE tank compression lz4 local zfs get sync NAME PROPERTY VALUE SOURCE tank sync standard default zfs get logbias NAME PROPERTY VALUE SOURCE tank logbias throughput local zdb | grep ashift ashift: 12 zpool status pool: tank state: ONLINE scan: scrub repaired 0B in 0 Agreed! I wasn't thinking of ZFS in terms of power saving but using a large pool to save power. unRAID 7. zfs set compression=lz4 mypool/mydataset In workloads with high read demands, ensuring that the Adaptive Replacement Cache (ARC) is properly sized can significantly improve performance. It makes no sense to talk of unRAID w/zfs or vice versa. As you may know, you dont get any speed increase, zraid functionality, but you get the Unraid Array positives of mixing drive capacity. For a good overview of ZFS, see this article. For me ZFS Master was keeping my ZFS disks from sleeping. alles klappt, wie bisher, inkl. More cores are better to enable higher compression. 3. For example, zfs devices are not formatted as such and it's a strong recommendation never to assign just a partition to a zfs pool. Specifically, zfs can do raidz levels reliably as compared to btrfs. Good point, thanks - haven't thought about the recordsize (of zfs) vs sectorsize (of the VMs file system) issue for my example. I suspect these are two separate issues, but could be loosely related. f. After turning on, I copied about 2,5 tb data from another identical 3tb disk (unassigned, xfs, without compression) When looking on the compression rate, its abaou 1. 1, have two 500G drives for basic array (Data and Parity) and then a ZFS pool for most of the storage. Proxmox Step 2: Enabling ZFS Compression. Reply reply In addition you may format any data device in the unRAID array with a single-device ZFS file system. Features like streamlined setup and better performance optimizations make virtualization on Unraid even easier via added support for VM I now did the same again, updated to rc3. (287): /usr/sbin/zpool set autotrim=off animzfs Apr 7 15:10:43 AnimNAS emhttpd: shcmd (288): /usr/sbin/zfs set compression=off Compression. Discover how to reformat a disk within your Unraid array to the robust ZFS file system (or any other file system) in this comprehensive tutorial. I also like the typical unRAID array for single disk spinning tasks like media server, using different varieties of HDDs etc. Im not sure about snapshots. 1 Now Available. Nero8762 This calculator is allowing for % of usable free space & slop space, unRAID may not be. In fact using zfs in those other products would be a better experience. My array currently consists of a 20 TB parity with (2) 18 TB array drives both formatted in XFS. 12 and above, leveraging the ZFS capabilities introduced in this version. Then again, compression was added to BTRFS as well. This worked without issue for me. Members; 51 Posted My understanding of the unRAID implementation of ZFS is that you can create a ZFS volume and add THAT to your array. e. unraid6. Autotrim and compression can be configured for the entire pool Hallo, mir wurde empfohlen das unRaid besser sein soll als Freenas oder Nas4Free. ZFS Dataset: A ZFS dataset can be thought of as a sort of advanced folder with features like compression, quota, and snapshot capabilities. The next step is export this game library ZFS pool to unraid, configure iSCSI on unraid and test again. Had to manually enter 'lx4' compression, '4KB' block, and 'NONE' for 'Primary cache' entries using ZFS Master utility. But it also supports trim on the entire pool, which is great news for SSD users. Decision time on to whether to make the array ZFS or unraid included weighing up the loss of individual disks powering down, multi-size disks in an array and the easier expansion (compared to ZFS). same at dataset level for zfs. So, for my new unraid/zfs box, would I be able to do things like snapshots and zfs-send to my backup box while still having the unraid advantage of using different size disks? Would unraid using zfs be able to take advantage of things like copy on write, sync writes, inline compression, etc?? Would I be able to use tools like sanoid/syncoid unraid is a storage operating system designed to provide an efficient and flexible storage solution for both home and small business users. In fact some people just use a usb drive to fulfill this requirement so it doesn't take away from sata, m. I cannot for the life of me get the zfs to appear properly in the GUI. 07. (also compression) as my server is a 13th gen i7 with decent memory ZFS extra overhead is not a problem. Help By k. Use the following command: sudo zfs get all [poolname]/[folder] | grep compressratio . Performance Impact : If the deduplication table exceeds available memory, ZFS will need to access the DDT from disk, significantly slowing down both read and write operations. My main unRAID system has been running a zfs pool under the plugin for releases below 6. I'm not sure it helped. TRIM, compression and other features are all available with compression with no limitations or further loss of security implications. 0-beta. 0 replies; 846 views; scot; March 19; Unraid not working on Mac By ALso if i have both SMB enable, the unraid and ZFS as you mentioned above, would that cause issues.

Data Compression: ZFS offers Every now and then i hear that my hdd drives on ZFS "zpool" are working at 100% and when i want to check in gui what is going on i find that it is not available as well as any docker container. I wonder if it might be possible to make it so that the pools are shown in a list and then the data sets are only shown / hidden by clicking the pool i. The default record size in ZFS is 128 KB, but this can be adjusted: You get all the benefits of ZFS (Compression, Encryption, Efficient Incremental Backup, Online filesystem defragmentation, Dynamic inode allocation, Copy on Write, Snapshots, Subvolumes, Deduplication, single / double parity, etc). Although I am ambivalent about compression on already compressed files like h264 and the even more compressed h265 - as the space saved ZFS's deduplication is most efficient when the DDT fits entirely in memory, with the rule of thumb being about 5 GB of RAM per 1 TB of deduplicated data. ensnare. 50x – Sadly it turns out Unraid overrides the compression setting for the pools on starting the array, so it defaulted to off for both my pools and one of them was set to zstd-2 which isn't even an option in Unraid. 40x, depending on where you look. KluthR. 1 Quote; Marshalleq. 2k Author; Posted October 13. Nun habe ich gesehen es gibt ein Plugin für ZFS. Compression can be configured as on or off, where on selects lz4.

Members; 968 Posted October 11, 2019 (edited) Hi, I have three basic questions about this plugin. My 9-5 is essentially "this is slow, make fast" for a data management/security company, and since basically every application out there has some persistent data to be managed, some OS/hardware to run it, and some way to connect to it, I end up knowing just a Update on my testing zfs with dedup/compression/zvol + iSCSI works also on unraid. On a note, currently, Unraid doesn't support ZFS native encryption for pools. Community Developer; 16. Hi, Here is an another companion plugin for the ZFS plugin for unRAID. Write speed around 30MB/s, sometimes even lower. If you want better compression in an already compressed file the only way to get there is to uncompress it back into it's raw elements and then recompress it using better compression methods. zfs pools on the other hand is a nice thing for VMs and dockers, considering the speed, bitrot protection and compression stuff, more like a cache drive on steroids. Also has better bitrot protection Snapshots only help with fat finger scenarios, they are not true backups at hardware level. I created a share called "Test" on only that disk with no secondary storage. It's often used for mirroring and backups. and lastly I like to disable access time zfs set atime=off SSD. When combined with the Linux KVM hypervisor, you can use it to make your systems functionally immortal. 30%) geschrumpft (Anzahl Files ist gleichgeblieben). Posted August Hi @mmm77, most of your assumptions are correct, Unraid can create an encrypted pool; this process encrypts the entire disk using LUKS so your data is always encrypted. 6 x 8TB drives in a single zDev on raidz1. 0) to modernize the plugin and switch from unRAID version detection to Kernel version detection and a general overhaul from the plugin. Tried 5 different NAS distros. Upgraded from 6. I've got a very basic ZFS disk: sdh 8:112 0 12. Deduplication and Compression on ZFS are nice as well. RSYNC from NVME to new single SATA disk (ZFS) parityless array through FUSE (Less than half the speed of XFS, about the same with ZFS compression on): about the same with ZFS compression on): The UNRAID method of data storage and backup was nice back when I had an assortment of disks, but now that I have dozens of the same types of The Prototype Test Box for the Gamers Nexus Server. Existing user? Sign In Sign Up Note, I was running ZFS Mirror with compression and trim enabled. I then created the ZFS Pool using 6 (8TB) HDD drives: zpool create -m /zfs zfs raidz2 sdf sdb sdc sdh sde sdd I then set ZFS compression to lz4 as recomended with: zfs set compression=lz4 zfs I then created datasets using: zfs create zfs/data and zfs create zfs/backup Unfortunately i dont know that there is an easy way to install it on unRAID. Settings up first Ubuntu 22. Then I set the disk back to ZFS - encrypted -> didn't work. We are splitting full ZFS implementation across two Unraid OS releases. 12正式版出来了，感觉最大的变化就是文件系统可以使用ZFS，请大佬提供无损升级ZFS文件系统教程。现阵列盘现在是采用xfs，缓存池是btrfs 另外请问zfs可以用作冷备大仓库，让所有盘都休眠吗，计划把家里12500主力UNRAID升级到ZFS，再直通一个盘给群晖放热 We are splitting full ZFS implementation across two Unraid OS releases. but running zfs for the entire storage array, not really any point, at least not in my usecase. Keeps timestamps and permissions etc. A community all about Baldur's Gate III, the role-playing video game by Larian Studios. enabling ZFS compression. We’re going to perform ZFS compression on our newly created pool. Well compression of iSCSI volumes would be a waste of time really since Windows would not be able to benefit from the compression savings (as it's not aware of the underlying ZFS system), but it would nevertheless be interesting to compare the results in case I would choose to use a NFS/shared folder solution in the future. 14-1 zfs-kmod-2. Read performance over Samba went from about 1. conf in the folder - ejected USB from my PC and plugged back into my server and now have the below result. In that share, I copied several very large media files into a "_test" folder (83 GB total). 12. Initial support in this release includes: Autotrim can be configured as on or off (except for single-device ZFS volumes in the unRAID array). I'm sitting between 80% and 90% utilization at any given time (8TB usable, ~1TB free). I would love to see examples in the wiki of what a btrfs drive corruption looks like when it happens in unRAID and then the typical steps to attempt and fix said corruption (like if a drive gets corrupt when writing data and then sudden power lose I see "Unraid" in MacOS Finder under Network, but can't connect. alexander, July 17. The cache pool running my docker containers use two NVMe drives in a raid0 (yep - I know the risk and make backups ) Since converting this to a zfs cache pool, my containers seem to be a bit sluggish. Although I am ambivalent about compression on already compressed files like h264 and the even more compressed h265 - as the space saved Unraid-Zfs: what is an dataset? Just as my last post, this is a rundown of what a dataset is, learned from someone who did not know anything (or extreme little) about zfs before it got added to unraid :) I really like the added functionality a dataset gives an unraid share. rsync: A fast, versatile utility for copying files and directories. Because its the "best" compression algorithm at the time, when you compare time needed to compression ration. Reply reply More replies More replies More replies More replies. Members Online • Sptzz. I just created a few pools on truenas core 13. Whilst this was only on 1 VM with 4 cores on unRaid as soon as compression was disabled the performance went back up. 7. zfs set compression=lz4 SSD.

Without it not much is left (just compression in Unraid) for worse support (aka less people run Unraid that way so you will have less support). VMs on ZFS work, even with the libvirt. I'm running a newer Epyc chip with ZFS and when compression is enabled I'm seeing some massive dips in drive performance. conf. 12+ Check if appdata is on a ZFS filesystem AND in its own dataset If so, take a snapshot and give it a unique name generated by the I will preface this by saying I am really new to all of the unraid/zfs fun but am learning and hope this is a reasonable spot for this post. One super important thing: when you’re enabling or disabling ZFS compression, you’re not actually changing any data on the ZFS The current unraid default when you enable compression on btrfs in 6. Since I encountered an issue with Disk 2, I did and completed a parity check, stopped the array, removed the disk Is there a migration guide for the ZFS plugin to native unRAID ZFS? I'm sure someone must've written up something, because I'm not the only one using this plugin, and it's clearly not a 0-step in-place upgrade. Initial support in this release includes: Support raid0, mirror, raidz1, raidz2 and raidz3 root profiles. Quote; Link to comment. I suspect there was a hw failure connected to my nvme0n1 configured as mirror drive of a zfs cache: Compression. returns the following: backup01/data compressratio 1. 12 RC on my backup server with a zpool consisting of 8x10TB SAS drives and I've been happy with the performance. If something is already compressed it's not going to make it super compressed. Something to do with having different partitions. Time will tell as Unraid may implement ZFS differently than say TrueNAS. Today I released in collaboration with @steini84 a update from the ZFS plugin (v2. The unRAID devs really need to get some sort of snapshot mechanism for the main pool. Answering your question about data being encrypted twice, Yes, ZFS is not aware of the I'm new to Unraid and I've been watching Spaceinvader One tutorials on YouTube to get my initial Unraid setup completed. 39 minutes ago, bmartino1 said: root@BMM-Unraid:~# zfs destroy vm-zfs/zfs_lxccontainers/PBS/ You will be able to select zfs as file system type for single unRAID array data disks. 1GB/s to 100 root@server:~ # zfs set compression=lz4 newvol How To Disable ZFS Compression. 12, planning to use zfs instead of the brtfs cache pool for my cctv and temp download pools, I might even move and expand my docker/appdata/vm ssds to it), but I think your main storage should be the main array. I had read that BTRFS was not recommended in a r5 scenario so I always either ran individual SSDs or mirrored two together. 1 Quote; ensnare. But ZFS supports replication, compression, duplication and encryption out of the box. I followed Spaceinvader One guide on how to set up a zfs pool (2x 4TB nvme plus 2x 4TB SSD) as a zpool support auto trim, all good and seems to work well Zfs has things like deduplication, compression, snapshots, and bitrot protection. A ZFS mirror can survive a drive failing because both disks contain a full copy of all the data (hence the term Unfortunately, Docker on ZFS still gives me trouble (just tried again to confirm, see the following pictures and description). A couple of days ago my Unraid NAS went unresponsive. Since that's 2 supported filesystems that can do it it would be worth having the option in the share Unraid wins in some other areas though particularly the user interface for docker and vms and the docker App Store. ich777. img residing on ZFS but as a security measure I still keep the libvirt. Sanoid also includes a replication tool, syn ZFS Pools New in this release is the ability to create a ZFS file system in a user-defined pool. I have to do *something* to keep my dataset intact, question is, what. I'm trying to allocate 1/2 my RAM. First, let's discuss compression. 01x or 99. For large-scale datasets, adjusting the block size with recordsize may optimize I/O performance. A collection of documentation I've written up surrounding UnRAID's use while running the ZFS filesystem I just switched from TrueNAS Scale to Unraid and am sharing my ZFS datasets via Samba in smb-extras. 1G or 2. For example, Plex spins when I try to Navigate from my With 6. Now we could just use one file system (/mnt/SSD I'm using BTRFS for my array and I wanted to enable compression on all the disks (it benefits my use case, the same data takes 1/6 less size on compressed disk). Future update will permit specifying 测试内容涉及大文件移动、缩略图生成和 4K 视频编辑，展示了各种设置的响应能力。视频最后讨论了分层存储系统，感谢频道成员，并邀请大家讨论 Unraid 和 TrueNAS。还预告了未来关于 Proxmox 和 PB It had no previous partition, and I let unRAID format it as ZFS (no compression). I activated compression for my iso-share but left it Overview #zfs for #unraid (Create, Expand and Repair ZFS Pool on Unraid) It looks like you can currently do it at command line, and once Unraid has it, I might do some testing when some spare disks to see what happens before I move my array. one disk would make an individual zfs-pool and zfs-folder (fs) for unraid) Does this, (kind of) ZFS RAID10 provides same level of redundancy in case of disk failure Is there any performance improvement? I plan to use ZFS with the default recordsize and lz4 compression Currently Im running some FreeBSD servers with ZFS mirror very successfully, does this (kind of) ZFS RAID10 array provides better performance? No ZFS compression is not a magic wand. The updated VM Manager includes enhanced functionality and performance, ensuring a smoother and more robust experience for those managing virtual machines. Some of the "fixes" claimed you had to remove the ZFS Master and ZnapZend, but Hi, In my Unraid array, I have five ZFS single-disk stripes, labeled Disk 1 through Disk 5, along with one parity drive. I've attached my diagnostics. zfs is great for those who need the performance ZFS also allows for snapshots for ransomware protection. 13 adds support for managing that in the GUI, i assume it'll just work? i was thinking about using my new 18tb mg09 as array drives in zfs (for easy zfs send/receive and compression). Personally I would NEVER use ZFS on single disks on my Unraid array. How script Works: I built ZFS for unraid in 2015 and as of March 2023 the original setup of 3x SSD + 2x HDD is still going strong running 24/7. On my existing SSD cache pool, I have a "Download" share (shows as exclusive access). Dabei bleibt die Flexibilität und Stromverbrauch (das ist noch abzuwarten) von Unraid und die Checksummenprüfung auf korrupte Daten von ZFS erhalten. Show Me The Gamers Nexus Stuff I want to do this ZFS on Unraid You are in for an adventure let me tell you. zfs create dumpster/test -o casesensitivity=insensitive -o compression=off -o atime=off -o sync=standard (ZFS verification) ZFS list I also have xattr set to sa and I am using the new compression type zstd-1. For zfs the command is zpool trim {poolname}. 2 replies; 542 views; k. It's a general ZFS calc, not specific to unRAID. I'm posting this in the General section as it's all eventually going to run the gambit, from stuff -single zfs formatted drives in the unraid array works just like xfs drives, parity work as normal etc, but you can use snapshots, compression, ram-cache (arc-cache), zfs-send (basically copy an ZFS can handle a vast amount of data while protecting against data corruption, allowing for snapshots, compression, and replication. Compression Encryption Send Receive / backup option Super reliable CoW file system unlike BTRFS in my opinion. : So comparing reliability between btrfs pool and xfs single is like comparing zfs to ntfs. Future update will permit specifying other algorithms/levels. zfs is an integrated storage management system, rather than just a file system. I've been working with zfs in enterprise environments since 15 years and I've only put deduplication into production once. I changed one of them to gzip-9 and zfs master stopped showing dataset info. After the upgrade, I converted my two cache pools to zfs. XFS gets all the testing, gets all the love. Overall far better for protecting against ransomware attacks due to snapshots than with xfs. Compression can be configured as on or off, where on selects lz4 I'm been a unraid customer since v5, love it and everytime it gets better! To me unraid only need two things to get perfect after 6. 1. 01:50:04 zpool scrub zpool Link to comment. Haven’t really noticed anything different besides being able to use compression now. Am I doing something wrong? Thanks so much in advance!!! Here's my dashboard too: unraid array: xfs (but i do one zfs disk as a snapshot backup target) It also has better compression options and other things. Posted February 27. 2023-12-19. If its on a default unraid Used heavily in Unraid Docker templates. set compression on lz4 bash: `zfs set compression=lz4 {{pool_name}}` I lurked this forum, likely a year ago, and my takeaway at the time was _don't use ssd only with unraid and zfs_, so I left a mental note to come back when ssds "were a thing". All your hard drives can be configured any way you want and doesn't have anything to do with the unraid array. I mean BTRFS doesn't even do a RAID 5/6 equivalent reliably anyway. If you format array drives as zfs, you get functions like compression and zfs-send. img in the standard folder to ensure it is not the . Jedoch scheiterte es immer an dem ZFS. Hi Very new unraid but look fantastic. I plan to add another HDD in the near future formatted in ZFS for sending snapshot backups from the Cache pool(s). Wenn Du auf ner Baby-CPU - egal ob mit/ohne AES-NI Support - (die falsche) compression aktivierst bis Du am Irschlogisch ;-)diese eingebauten Features Just be aware cache in unraid isnt cache its unique data, its more of storage tiering. The rule of thumb is generally 250MB/TB for best performance, but it works with less. It was my fault, I forgot to disable bitlocker on the test laptop.
