ZFS pool change offline disk

[Andrea Carnevali]

Hi.
I should replace a bad disk in a poll zfs raid 1 consisting of 2 disks.
Before intervening as a test, I replicated the problem in the laboratory to verify the correct procedure.

root@pvetest:~# zpool status -v
  pool: rpool
 state: DEGRADED
status: One or more devices has been taken offline by the administrator.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Online the device using 'zpool online' or replace the device with
        'zpool replace'.
config:

        NAME                                             STATE     READ WRITE CKSUM
        rpool                                            DEGRADED     0     0     0
          mirror-0                                       DEGRADED     0     0     0
            ata-HP_SSD_S700_250GB_HBSA21461100352-part3  ONLINE       0     0     0
            13358101648816339960                         OFFLINE      0     0     0  was /dev/disk/by-id/ata-HP_SSD_S700_250GB_HBSA21461100339-part3

I removed the damaged disk and inserted a new one that matches the working one.
Now I would like to figure out if I need to recreate the partitions before doing the zpool replace.

 zpool offline rpool 13358101648816339960

If I directly replace the disk then I don't find the same partitioning scheme in the new disk.

Can you help me with the correct command that I should use?

root@pvetest:~# fdisk -l

See here the paragraph "Changing a failed bootable device". But that is for PVE 6.4/7.0/7.1 with the new proxmox-boot-tool. For PVE installed with 6.3 and earlier there were other commands. Looks like the wikis versioning isn't helping here because the wiki will be automatically created based on the documentation.
