Single hdd zfs pool, removed from system, attempt to mount on other comp

[jackdinn]

I think I might have made a drastic mistake in my understanding and assumptions of ZFS and truenas.

I wanted to have 4/5 drives as raidz2 and use them for various truenas functions.

Furthermore, I wanted to have a couple of separate individual drives that I would replicate backup data to so that in theory if the whole system broke I could take out one of these single drives (striped pool), connect them to any other computer and at least access what I had backed up on there.

I attempted to do this.

On a Manjaro system i plugged in one of the single drive pools. I kinda struggled to get anything mounted and gain access to the backup files. Eventually I thought I had managed it because the folders were showing but all the files were missing?

I have since put the single drive back into my nas system and it seems fine, all the files in the backup folders are still there.

What have i done wrong?

Code:

❱sudo zpool import
pool: dellhdd
id: 13983114661322384791
state: ONLINE
status: Some supported features are not enabled on the pool.
(Note that they may be intentionally disabled if the
'compatibility' property is set.)
action: The pool can be imported using its name or numeric identifier, though
some features will not be available without an explicit 'zpool upgrade'.
config:

dellhdd     ONLINE
sdb2      ONLINE

❱zfs list

The command you're looking for is zpool import dellhdd.

The command you're looking for is zpool import dellhdd.

❱sudo zpool import -f dellhdd
