Hi,

Partition your new disk exactly as the existing disks.

zpool attach rpool /dev/disk/by-id/ata-WDC_WD2000F9YZ-09N20L1_WD-WMC5C0D7E3DU-part3 /dev/disk/by-id/<new-disk>-part3

And then, depending on if you’re using grub or proxmox-boot-tool, install the bootloader onto the new disk.

Subject [PVE-User] add disk back to raid10

Hello to all,

I'm playing with zfs arrays. Here you can see former RAID10 because there is 
mirror-0 missing as such , because I unintentionally detached all disk 
references from this mirror-0 that used to be 2-disk mirror vdev for this 
raid10.

1. raid10 was OK  .... this is also boot raid10

2.  I physically removed one disk disk and mirror-0 became degraded

3. after lot of steps in order to replace one disk, put another-new and get all boot 
staff needed  and after lot of unsuccessful tries I unintentionally ended up detaching 
all references of old "faulted" disk and mirror-0 was gone

4. Now I have unnormal raid with two striped vdevs (see below), but one of them 
is just one disk , and the other one is regular mirror(-1)

So, now I'm trying to attach/add new disk to this raid10 but in order to get mirror-0 like it was 
before  ....   How can I reference "add" or "attach" to make mirror-0 again 
(consisting of ata-WDC_WD2000F9YZ-09N20L1_WD-WMC5C0D7E3DU-part3  and the new disk )  ?


Thank you very much in advance
