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 nowSources:
