Question about drive labels

OpenZFS
1

Using Ubuntu server, headless. Have a bunch of drives in my pool - how can i get the labels to show up for sda, sdb, and sdc like for the remainder? Useful for when drives fail (as happens occasionally, and thankfully not four drives in a row).

root@box:~# zpool export evilpool ; zpool import -d /dev/disk/by-id evilpool

Note that you may not get the exact labels you want this way, since /dev/disk/by-id typically contains ata, SCSI, and wwn labels for the same drives. If that ends up being the case, you can just mv the labels you don’t like to /tmp, then import, then mv them back from /tmp into /dev/disk/by-id.

And that’s if you’re feeling especially careful–those labels are automatically generated at each system boot, so sloppier/less-careful admins frequently just rm the ones they don’t want, knowing that the system will repopulate them on the next boot anyway. :slight_smile:
