Proxmox installed on zfs - partition problem

[Masterno12]

Hello,

I'am new to proxmox and before switching i've done some test.

I installed proxmox on a zfs pool:

config:



        NAME                                                      STATE     READ WRITE CKSUM

        rpool                                                     ONLINE       0     0     0

          mirror-0                                                ONLINE       0     0     0

            ata-SPCC_Solid_State_Disk_AA20220912875465757-part3    ONLINE       0     0     0

            ata-SPCC_Solid_State_Disk_AAAA000000765767765-part3  ONLINE       0     0     0



errors: No known data errors

i remove the ata-SPCC_Solid_State_Disk_AA202209128756756388 disk and i replaced it ,

zpool replace rpool ata-SPCC_Solid_State_Disk_AA202209128756465757-part3 ata-SPCC_Solid_State_Disk_AA7456789889

It work, great.
But the problems is for the partitions. If the other disk failed too, part1 and part 2 are lost and the system dont boot.

So my question is on do i replace correctly a disk in this scénario ?

See the wiki paragraph "Changing a failed bootble device": https://pve.proxmox.com/wiki/ZFS_on_Linux#_zfs_administration

Or the Proxmox manual about the partitions for the bootloader.
