[PVE-User] add disk back to raid10

[Tonči Stipičević]

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
