[SOLVED] Difficulty importing zfs pool into new proxmox server

[PhilGlau]

Hi, I'm fairly new to proxmox and experimenting in a home lab to learn it.

I had a ZFS pool on one ProxMox VE server called 'srv08'. I was using the storage as additional drive space for various VMs . Everything was working fine and there were no errors on the ZFS pool.

My pool name is 'zfs_pool' shown here attached to srv08:


I exported the pool from srv08 using:

zpool export zfs_pool
shutdown

and received no errors.
On srv11 (standalone), I attached the drives and ran:

zpool import -f zfs_pool

Which worked and zpool status provides:

  pool: zfs_pool
 state: ONLINE
  scan: scrub repaired 0B in 06:04:01 with 0 errors on Sun Nov 10 06:28:02 2024
config:

    NAME        STATE     READ WRITE CKSUM
    zfs_pool    ONLINE       0     0     0
      raidz1-0  ONLINE       0     0     0
        sdc     ONLINE       0     0     0
        sdb     ONLINE       0     0     0
        sda     ONLINE       0     0     0

errors: No known data errors

And zps list shows the various disks that were attached to VMs on srv08.

root@srv11:~# zfs list
NAME                     USED  AVAIL  REFER  MOUNTPOINT
zfs_pool                13.5T   934G   128K  /zfs_pool
zfs_pool/vm-106-disk-0  3.05T  3.18T   796G  -
zfs_pool/vm-106-disk-1  10.2T  3.87T  7.20T  -
zfs_pool/vm-108-disk-0   305G  1.10T   107G  -

However, under the Datacenter->srv11 it's not showing up as storage as it had on srv08.


I feel like I'm missing some simple step here.

Thank you in advance for any help you can provide.

Additional Information:
I updated the /etc/pve/qemu-server/XXX.conf files to reference the respective vm-XXX-disk images, ran qm rescan but when I attempt to boot those VMs I get "TASK ERROR: storage 'zfs_pool' does not exist" which I'm almost certain has to do with the pool not showing up under Datacenter->srv11 referenced above.

I think I figured it out.

I needed to go to 'Datacenter' ==>> Storage ==> Add to add the pool

Once I did that the VMs booted and 'zfs_pool' appeared under srv11 in my Datacent

zpool import -a -f -d /dev/disk/by-id

Is what you want; don't use short devnames for the ZFS pool devices
