[SOLVED] ZFS scrubbing does not work anymore on Kernel 6.14.11 (and cannot upgrade to 6.17.X because of NVidia)

Hi there,

I'm facing a bit of a situation right now on my NAS running Proxmox 9.1.5

• Userspace tools have been upgraded to 2.4.0
• Module is still on 2.3.4 in kernel 6.14.11
• Upgraded the pools already (I thought it was the issue)
• Scrub command fails telling to align both
• I cannot upgrade to 6.17.X because of NVidia
  • Currently pinned 6.14.11 to have GPU passthrough working for AI workloads

root@pve-nas-2:~# zpool version
zfs-2.4.0-pve1
zfs-kmod-2.3.4-pve1

root@pve-nas-2:~# zpool scrub dpool
cannot scrub dpool: the loaded zfs module does not support an option for this operation. A reboot may be required to enable this option.

What should I do in such scenario? Downgrade ZFS userspace tools? Will it work if pools have been upgraded already?

Thanks,

D.

I solved it by removing the kernel pinning, removing all Nvidia drivers on both host and all LXCs to then move to 6.17 and 580 drivers.

Everything works again, including ZFS scrubbing.
