Hi all,

have a fresh installed pve on a SSD Mirror pool, but degraded. How can i remove the missing drive and re add?
Code: 
# zpool status -x
  pool: rpool
 state: DEGRADED
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.
action: Replace the device using 'zpool replace'.
   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-4J
config:

        NAME                                        STATE     READ WRITE CKSUM
        rpool                                       DEGRADED     0     0     0
          mirror-0                                  DEGRADED     0     0     0

thx a lot and cheers
 
Best way is to have a spare slot disk usable on your host.
If present, you cannot use "zpool replace"
But, the safely use of them is with zpool offline mode.

On a boot zfs mirror (/raidz*) a "zpool replace" (iO for option pools) alone and even a spare disk alone would NOT do the full job (works only for part3), see link by leesteken !!

thx a lot for all your answers,

but just rebuild from scratch. cleaned all the drives with wipefs created new pools and now all looks fine.

cheers
 
zpool detach rpool 2733430748360847942

The create a new partition table:
sgdisk /dev/disk/by-id/ata-SSD_1642403003004585 -R </dev/disk/by-id/new-device>

Create a uniq UUID of the device:
sgdisk -G </dev/disk/by-id/new-device>

zpool attach rpool ata-SSD_1642403003004585-part3 </dev/disk/by-id/new-device-part3>
