Greetings.
I’m looking for a little help with a ZFS pool that I’ve recently migrated from an Ubuntu machine to my new Arch Linux machine.
I imported the pool using the zpool import -f tank
and it reported my cache drive as faulted, but my storage drives are working fine. Its a raidz2 with 5 drives. The weird thing is, its reporting the wrong drive as the cache. Its listing sde
, when it should be sdg
. Notice that sde
is also listed as a storage device.
❯ zpool status
pool: tank
state: ONLINE
status: One or more devices could not be used because the label is missing or
invalid. Sufficient replicas exist for the pool to continue
functioning in a degraded state.
action: Replace the device using 'zpool replace'.

My actual cache drive is happily waiting to be used: see /dev/sdg:

I’m not sure how to replace the cache drive with the correct one. The replace command throws an error:
sudo zpool replace tank sde
/dev/sde is in use and contains a unknown filesystem.
