I have a zpool with four disks:

  • /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J9AZB03256
  • /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S2NWJ50BB01630
  • /dev/disk/by-id/ata-SAMSUNG_HD103UJ_S13PJ90S328545
  • /dev/disk/by-id/ata-ST1000DM003-1CH162_Z1D8NBZ6

I tried and get:

sudo zpool list
no pools available

sudo zpool -DFa
no pools available to import

For each disk I tried using zdb like below and get similar result:

sudo zdb -el /dev/disk/by-id/ata-ST1000DM003-1CH162_Z1D8NBZ6-part1

And then using the suggetions in zfs-import-unable-to-find-any-pools I tried and got

sudo zpool import -D -f zfs-array-0
cannot import 'zfs-array-0': no such pool available

I tried and got too

sudo zpool import -ad /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J9AZB03256-part1 -ad /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S2NWJ50BB01630-part1 -ad /dev/disk/by-id/ata-SAMSUNG_HD103UJ_S13PJ90S328545-part1 -ad /dev/disk/by-id/ata-ST1000DM003-1CH162_Z1D8NBZ6-part1
no pools available to import

The zpool was originally create in proxmox, I tried the same commands in there and in the manjaro, and get alls the same result. I'm using zfs-0.8.5-1 in manjaro. And zfs-0.8.4 in proxmox.

Finally, I'd like to know if someone has any idea how can I import the zpool or how to access the data in the zpool? And why this happened?

I could import the pool by using the first partition of each disk. Something like this:

# zpool import -d /dev/disk/by-id/ata-disk1-part1 \
    -d /dev/disk/by-id/ata-disk2-part1 \
    -d /dev/disk/by-id/ata-disk3-part1 \
    pool_name

My system got broken after I migrated from Ubuntu LTS 20.04 to 22.04.

I've created an USB Stick and booted into live mode.

There I could do "sudo zpool import -d /dev/disk/by-id/" (sudo was mandatory).

By doing so I've seen that in my case it was *-part4. Here you'll also see the pool name, in case you've forgot it.

In the last step I've monted as mentioned in Ismael's post:

zpool import -d /dev/disk/by-id/ata-disk1-part1 -d /dev/disk/by-id/ata-disk2-part1 -d /dev/disk/by-id/ata-disk3-part1 pool_name

Once the pool is mounted and if the data is imporatant, the first thing you should do is a backup to an usb drive or something similar.
