[PVE-User] add disk back to raid10

[Mark Schouten]

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 )  ?
