Hello:

On a proxmox server I configured a zfs raid with two mirrored disks, the question is if I can restore that raid on another proxmox server because that one is out of service and I need to recover the backups who are in that raid.

greetings
 
Hi, yes this should be possible. Transfer the disk and issue a zpool import command. This should detect the zpool and allow you to import it via the zpool import <poolname> command.
 
if the pool has the same name you have to add an alternative name

Bash:
zpool import
should show you the name and the poolid

Code:
pool: testpool-z2
     id: 4186405337650802820
  state: ONLINE
status: The pool was last accessed by another system.
 action: The pool can be imported using its name or numeric identifier and
    the '-f' flag.
   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-EY
 config:

    testpool-z2                ONLINE
      raidz2-0                 ONLINE
        /home/ubu/3.diskimage  ONLINE
        /home/ubu/4.diskimage  ONLINE
        /home/ubu/5.diskimage  ONLINE
        /home/ubu/6.diskimage  ONLINE



Bash:
zpool import -f 4186405337650802820 oldpool -R /OLDROOT
