Built zfs-2.0.0-rc5 for 6.8.3 & 6.9.0-beta30 *see the first post to see how to enable unstable builds

I´m sorry, but I dont use Windows You could send a question to this awesome podcast: https://2.5admins.com/ It has Jim Salter the author of Sanoid/Syncoid and the literal king of ZFS Allan Jude

Good idea, I completely forgot to separate the stable builds from the RC version. I upgraded the plugin so that by default you install the cached version if available. If not the plugin check for a stable version by default. However you can touch a file on disk and enable unstable builds (like the 2.0.0 RC series) #Enable unstable builds touch /boot/config/plugins/unRAID6-ZFS/USE_UNSTABLE_BUILDS rm /boot/config/plugins/unRAID6-ZFS/packages/* #Then reboot #Disable unstable builds rm /boot/config/plugins/unRAID6-ZFS/USE_UNSTABLE_BUILDS rm /boot/config/plugins/unRAID6-ZFS/packages/* #Then reboot The builds are pretty much vanilla ZFS and you can check the build scripts on Github: https://github.com/Steini1984/unRAID6-ZFS/blob/master/build.sh (to build latest ZFS) https://github.com/Steini1984/unRAID6-ZFS/blob/master/build_github.sh (to build custom versions like RC) I feel your pain and it´s incredibly frustrating when the server has issues! I remember having incredible problems with my server a few years back. Random disks failing, processes crashing and all around pain. Took me probably a week of debugging and the solution was a new PSU. Hope you can fix your problems and I really hope that at least ZFS in not the culprit

Rebuilt zfs-2.0.0-rc4 for unRAID 6.8.3 & 6.9.0-beta30

Sorry my bad. Had the rc3 files cached rebuilding now Sent from my iPhone using Tapatalk

built zfs-2.0.0-rc4 for unRAID 6.8.3 & 6.9.0-beta30

I have had problems with that before and I had to do zfs destroy dataset rm -rf mount point Then zfs destroy dataset again Sent from my iPhone using Tapatalk

First off here you can see the build script. https://github.com/Steini1984/unRAID6-ZFS/blob/master/build.sh

So what happens is that the plugin first checks if you have a locally cahed package to install in /boot/config/plugins/unRAID6-ZFS/packages/ and if not it check on github. If I understand correctly you are running unRAID 6.8.3 stable and want to run zfs 2.0.0-rc3? This is what I did to achive what you want. Have the plugin installed and run these commands rm /boot/config/plugins/unRAID6-ZFS/packages/zfs* wget -O /boot/config/plugins/unRAID6-ZFS/packages/zfs-2.0.0-rc3-unRAID-6.8.3.x86_64.tgz https://www.dropbox.com/s/wmzxjyzqs9b9fxz/zfs-2.0.0-rc3-unRAID-6.8.3.x86_64.tgz?dl=0 wget -O /boot/config/plugins/unRAID6-ZFS/packages/zfs-2.0.0-rc3-unRAID-6.8.3.x86_64.tgz.md5 https://www.dropbox.com/s/3onv1qur26yxb7n/zfs-2.0.0-rc3-unRAID-6.8.3.x86_64.tgz.md5?dl=0 Before you reboot you can run this command and test if everything went as expected cat /etc/unraid-version && md5sum /boot/config/plugins/unRAID6-ZFS/packages/zfs-2.0.0-rc3-unRAID-6.8.3.x86_64.tgz && cat /boot/config/plugins/unRAID6-ZFS/packages/zfs-2.0.0-rc3-unRAID-6.8.3.x86_64.tgz.md5 and you should get this exact output: version="6.8.3" 8a6c48b7c3ff3e9a91ce400e9ff05ad6 /boot/config/plugins/unRAID6-ZFS/packages/zfs-2.0.0-rc3-unRAID-6.8.3.x86_64.tgz 8a6c48b7c3ff3e9a91ce400e9ff05ad6 /root/mount/zfs-2.0.0-rc3-unRAID-6.8.3.x86_64.tgz then you can reboot and can confirm if it worked like expected: root@Tower:~# dmesg | grep ZFS && cat /etc/unraid-version [ 33.429241] ZFS: Loaded module v2.0.0-rc3, ZFS pool version 5000, ZFS filesystem version 5 version="6.8.3"

Check this thread out since it has some good info: https://www.reddit.com/r/zfs/comments/ew9zjm/turning_off_dedup_question_for_someone_more/

Maybe you can just use dedupe on the dataset that houses the builds? Sent from my iPhone using Tapatalk

It is probably the dedup that is killing you. I want to steal this quote "Although it sounds cool, deduplication is rarely worth it. It usually creates a lot of memory problems " REF: https://bigstep.com/blog/zfs-best-practices-and-caveats

You are using almost all of your memory. You can either use a smaller arc or add swap... maybe both Adding swap: #first create a 8gb zvol where <pool> is the name of your pool: zfs create -V 8G -b $(getconf PAGESIZE) \ -o primarycache=metadata \ -o com.sun:auto-snapshot=false <pool>/swap #then make it a swap partition mkswap -f /dev/zvol/<pool>/swap swapon /dev/zvol/<pool>/swap #to make it persistent you need to add this to your go file: swapon /dev/zvol/<pool>/swap

Ok so the limit is working, but what about: free -g

can you paste the output of arcstat

Built zfs-0.8.5 for unRAID-6.8.3 I also built zfs-0.8.5 for unRAID-6.9.0-beta30 for those who want to try the unRAID beta but stay on the latest stable ZFS version. To install 0.8.5 on beta30 you have to run these commands and reboot: rm /boot/config/plugins/unRAID6-ZFS/packages/zfs* wget -P /boot/config/plugins/unRAID6-ZFS/packages/ https://github.com/Steini1984/unRAID6-ZFS/raw/master/packages/zfs-0.8.5-unRAID-6.9.0-beta30.x86_64.tgz wget -P /boot/config/plugins/unRAID6-ZFS/packages/ https://raw.githubusercontent.com/Steini1984/unRAID6-ZFS/master/packages/zfs-0.8.5-unRAID-6.9.0-beta30.x86_64.tgz.md5

Added zfs-2.0.0-rc3 for unRAID-6.9.0-beta30

I run it every minute, but for a simple snapshot without replication znapsend might be easier to setup Sent from my iPhone using Tapatalk

I do a scrub, then a trim every month via the user scripts plugin. ref: https://github.com/openzfs/zfs/commit/1b939560be5c51deecf875af9dada9d094633bf7

Well to be fair you are running a beta version of unRAID with a release candiate of ZFS so things like this are more likely with a combination like that. But just a few hours ago there was a new rc for zfs and i´m building it now. Should be up in 1-2 hours it´s online now https://github.com/openzfs/zfs/releases/zfs-2.0.0-rc3 The best bet is to run this command and reboot rm /boot/config/plugins/unRAID6-ZFS/packages/zfs*
