Try to add mpt3sas.max_queue_depth=10000 to your kernel boot line in /etc/default/grub or /etc/kernel/cmdline

You can download deb directly - http://ftp.no.debian.org/debian/pool/main/d/debsums/debsums_3.0.2.1_all.deb Using Live distro you can mount rpool and then bind mount /dev /sys /proc , chroot and use it as normal OS. In that environment you can install debsums, look at files and do changes.

It should make no problem to install but If you are struggling you can download directly - https://packages.debian.org/bookworm/all/debsums/download

Mixing different performance disks will lower your all disk performance to the lowest disk performance.

I would give a shot with #debsums for some curiosity

If you want to have auto healing using single disk then you have to set copies more than 1

Looking to your storage config your ZFS nvme_cluster pool must have mount point to /nvme_cluster rootfs should be: nvme_cluster:subvol-122-disk-0,size=32G

It is good to play with half way broken HDD to understand how filesystem react to the problems.

If you are connecting to Windows VM you can use this manual - https://www.itechtics.com/use-multiple-monitors-rdc/ I think the same could be achieved with Linux too.

Old thread but I have the same problem. If I set ram as hotplug and size 122880: TASK ERROR: memory size (122880) must be aligned to 4096 for hotplugging If I change to 123904: Kernel panic - not syncing: System is deadlocked on memory If I remove ram from hotplug and set the size 122880...

BTW is it standalone server or cluster ?

Lets begin to fix it from the ZFS point. Is your nvme_cluster ZFS pool dedicated to VM data? Then lets set his mountpoint to /nvme_cluste or /media/nvme_cluste as I do. #zfs set mountpoint=/nvme_cluste nvme_cluste

First of all - Why you want to use ZFS? All other stuff can do it too: H/R, mdadm, LVM, filesystems, etc. But none of them do data integrity check. Except others filesystems like btrfs. If you don't need data integrity validation before it reach program then use regular tools and by happy...

I see nvme_cluster mount point is / Doesn`t it overlaps with rpool ? Or your OS is in nvme_cluster ? I think this is how it should be. I see you are doing small mistakes in every step.

Mounting in Live CD you can use -R : zpool import pool -R /another/mount/point So you could do what you need without mixing with Live CD / mountpoint Or -N : Import the pool without mounting any file systems. p.s. it is OK for /rpool/PVE and /rpool/DATA to be empty

Don't know how to help you but I use Jellyfin with disabled transcoding and I watch using Jellifin player on computer or on phone.

If zpool list show empty did you tried zpool import ?

BTW nvme_cluster/vm-123-disk-0 you can access from host in /dev/zvol/nvme_cluster/vm-123-disk-0 or /dev/zvol/nvme_cluster/pve/vm-123-disk-0 ( depend on storage config) From there you can mount/format virtual disk/block volume. Just do it then VM using this storage is off.

Hello blastmun As I can see it is filesystem in ZFS, not a block volume This config search for the file, not catalog. try to remove .raw And make sure you can access files /nvme_cluster/subvol-122-disk-0 from host
