Hello,
My lxc containers that is on zfs pool unexpectedly stopped working. When I’m trying to start them, lxd gives: Error: Required tool 'zpool' is missing
But zpool is NOT missing:
which zpool
/sbin/zpool
And I can run zpool.
lxd version 5.12. I’ve tried to uninstall it and install again, but now I have no zfs support (in lxd init it doesn’t offer zfs).
modinfo zfs gives

How to solve it? Now I copy all my containers to another server, then I’ll try to reinstall all system and move lxd files back, so I have little time to try repair something on this server.
