Hello, I have had a pool of two hard drives in a mirror pool for some time but the OS got corrupted and I reinstalled the OS. Now I am on Linux Mint and my pool does not appear any more. When I use zpool import it says no pool available to import, I have looked around online and found you can import a zpool by specifying the drives, so I used zpool import -f -d /dev/sda1 -f -d /dev/sdb1 internal I get back my pool

pool: internal state: ONLINE scan: scrub repaired 0B in 00:08:39 with 0 errors on Tue Jun 18 18:38:40 2024 config:

NAME        STATE     READ WRITE CKSUM
internal    ONLINE       0     0     0
  mirror-0  ONLINE       0     0     0
    sdb     ONLINE       0     0     0
    sda     ONLINE       0     0     0

errors: No known data errors

But I am unable to mount the pool, zfs mount internal returns

cannot mount 'internal': legacy mountpoint use mount(8) to mount this filesystem

I tried using mount but I am not having any success, saying mount: internal: can't fin in /etc/fstab.

Is there any chance to get this pool back on the computer or is it a lost cause.

Thank you for the help.

The trick for this one is mount -t zfs -o zfsutil internal /mnt/some/path

Assuming the root dataset is mountable. If you have a -o canmount=off on the dataset it will refuse to mount.

If it's -o mountpoint=legacy then you don't need -o zfsutil, but still need to provide both the source and destination paths. Otherwise you'll get the fstab error because mount can't figure out what to mount or where to mount it.

It states it can't find it in /etc/fstab. So do you have it there? And does it have the correct ID?

(I don't know how zfs pools work, I'm just going of what the mount command said)
