ZFS pool

ZFS

Pool couldn't be mounted

If after a system update the ZFS pool can't be mounted, the issue could be the corrupted ZFS cache.
To fix that run the following commands:

# First create a backup
mv /etc/zfs/zpool.cache /etc/zfs/zpool.cache.bkp

# Enable relevant services if they aren't already
systemctl enable zfs-import-scan.service
systemctl enable zfs-import.target
reboot now

# This is optional, you could the pool if you want,
# but after the restart at the end it should be mounted automatically
zfs mount POOLNAME

# Execute this line for every ZFS pool
zpool set cachefile=/etc/zfs/zpool.cache POOLNAME

update-initramfs -u -k all
reboot now
