[SOLVED] ZFS causes kernel panic after power outage

[mert98]

Hello all, I am running a Proxmox server on version 7-1.2, few days ago i have experienced a power outage which causes system to fail at boot. When i connect a monitor to display, i saw that ZFS triggers kernel panic and system boot stucks.

After that i have booted into recovery kernel, and typed zpool status it says no pools avalaible then i typed zpool import, i can see all my pools after tried to import pools manualy i saw that a single pool was causing the problem which was attached to VM. Since VM was set to start at boot decided to change it from cfg files but could not find qemu-server files under /etc/pve/.
So i decided to disable zfs autoimport from /etc/default/zfs i have also edit kernel parameters and add zfs.zfs_autoimport_disable=1and i typed systemctl disable zfs-import-cache.service and systemctl disable zfs-import@POOLNAME but still getting zfs kernel panic after rebooting and failing to boot in shell. I already reffered to this thread but no help. Are there any other suggestion for booting system up ?

I suggest running memtest86+ to ensure your RAM didn't get damaged or anything, just in case.

Tried to run memtest86+ from grub menu gives me nothing but black screen. Tried to update kernel to pve-6.1 but no help.

SOLUTION: I decided to remove the disk with the problem. I tried importing all the pools manually and noticed that one of them was causing a kernel panic when using the zpool import command. So, I checked the SSD's serial number from the zpool import output and removed it from the PC. Then, I booted from the old kernel. Everything seems to be running well for now. I hope someone finds this useful.
