I created my first zpool the other day, assigning by drive letter, and found that when I rebooted it was degraded. Upon closer inspection, I realized that my drive letters had changed with reboot, so I figured I should do it using UUIDs.



I took a look at blkid and saw that both drives had identical uuids, presumably because they are mirrored. So I destroyed the pool and created new partition tables on the disks. When I ran blkid again, I saw that the drives no longer had UUIDs, just a PTID. This led me to realizingt that UUID is a property of a filesystem, not the drive itself.



So, I tried using /dev/disk/by-id/ both with the UUID of the formatted drive, and the PTID of the unformatted drive. Neither worked.

some of the threads I looked at led me to look at /etc/default/zfs
I found that the relevant line was commented out, but I wasn't sure what to make about the comments above it, which are worded in a way that confuses me:



# Specify specific path(s) to look for device nodes and/or links for the
# pool import(s). See zpool(8) for more information about this variable.
# It supersedes the old USE_DISK_BY_ID which indicated that it would only
# try '/dev/disk/by-id'.
# The old variable will still work in the code, but is deprecated.
#ZPOOL_IMPORT_PATH="/dev/disk/by-vdev:/dev/disk/by-id"


So, my question is, can I directly create zpools using a unique and permenant identifier, such as serial number? Or is there another way to create them by UUID that actually works?



I am using ZFS on Ubuntu Server 18.04

      some of the threads I looked at led me to look at /etc/default/zfs
      I found that the relevant line was commented out, but I wasn't sure what to make about the comments above it, which are worded in a way that confuses me:



      # Specify specific path(s) to look for device nodes and/or links for the
      # pool import(s). See zpool(8) for more information about this variable.
      # It supersedes the old USE_DISK_BY_ID which indicated that it would only
      # try '/dev/disk/by-id'.
      # The old variable will still work in the code, but is deprecated.
      #ZPOOL_IMPORT_PATH="/dev/disk/by-vdev:/dev/disk/by-id"


      So, my question is, can I directly create zpools using a unique and permenant identifier, such as serial number? Or is there another way to create them by UUID that actually works?



      I am using ZFS on Ubuntu Server 18.04



      Edit: Further attempts
      I also tried the advice here: https://ubuntuforums.org/showthread.php?t=2087726



      user@ubuntu:~$ sudo zpool create nvme-tank mirror nvme0n1 nvme1n1
      user@ubuntu:~$ sudo zpool export nvme-tank
      user@ubuntu:~$ sudo zpool import -d /dev/disk/by-id nvme-tank


      But now I don't see them in blkid at all:
