Hi, the zfs userspace .deb package versions can be out of sync with the kernel driver zfs kernel module version number. This can be seen in the output of

$ zfs version

For example on my test system I have:

$ sudo zfs version
zfs-2.1.4-0ubuntu0.1
zfs-kmod-2.1.5-1ubuntu2

Because I have a newer kernel version, than userspace tooling (I am testing upgrades). Or vice versa.

This particular bug is fixed in zfs 2.1.4-0ubuntu0.1 or higher, which is included in linux 5.15.0-43.46 or higher (or kernels based of it). Thus without upgrading zfs packages, one can reboot into newer kernel, which has never zfs, and things should be fine.

If anyone is having issues, please provide output of:

uname -r
sudo zfs version
