I have a ZFS pool that I made on proxmox. I noticed an error today. I think the issue is the drives got renamed at some point and how its confused. I have 5 NVME drives in total. 4 are supposed to be on the ZFS array (CT1000s) and the 5th samsung drive is the system/proxmox install drive not part of ZFS. Looks like the numering got changed and now the drive that used to be in the array labeled nvme1n1p1 is actually the samsung drive and the drive that is supposed to be in the array is now called nvme0n1.

root@pve:~# zpool status
  pool: zfspool1

status: One or more devices could not be used because the label is missing or
        invalid.  Sufficient replicas exist for the pool to continue
        functioning in a degraded state.

Trying to use the zpool replace command gives this error:

root@pve:~# zpool replace zfspool1 7987823070380178441 nvme0n1p1
invalid vdev specification
use '-f' to override the following errors:
/dev/nvme0n1p1 is part of active pool 'zfspool1'

where it thinks 0n1 is still part of the array even though the zpool status command shows that its not.

Can anyone shed some light on what is going on here. I don’t want to mess with it too much since it does work right now and I’d rather not start again from scratch (backups).

I used smartctl -a /dev/nvme0n1 on all the drives and there don’t appear to be any smart errors, so all the drives seem to be working well.

Any idea on how I can fix the array?

    I didn’t rename them. I suspect it happened during a reboot or maybe a bios update that I may have done last month.

    How do I clear or repair it?

      The device names and aliases in /dev don’t just simply change between reboots. Something else happened here.

      What are the path or IDs of the drives that are in there now under /dev/nvme*?

        Are you sure about that? Ever hear about this supposed predictable network names in recent linux versions? Yeah those can change too. I was trying to set up a new firewall with two internal NICs plus a 4-port card, and they kept moving around. I finally figured out that if I cold-booted the NICs would come up in one order, and if I warm-booted they would come up in a completely different order (like the ports on the card would reverse which order they were detected). This was completely the fault of systemd because when I installed an older linux and used udev to map the ports, it worked exactly as predicted. These days I trust nothing.

        I may have done a bios update around the time it went down, I don’t remember for sure but I haven’t added to physically changed the hardware in anyway. Its working now with the above suggestions so thanks!
