Hi,
I have a remote system which had a GRAID setup (RAID1) and something went wrong which rendered it unbeatable. I got some remote hands to boot the USB installer and thought I would be clever and create a RAID array with a single disk like so:

graid label -f Intel r0 RAID1 ada0

I then finished the install and could mount the other disk and recover all of the data from it, so I then deleted the old RAID on the other disk and add it to the array, ie

graid delete r1
graid insert -v r0 ada2

(The disks are ada0 and ada2)

Unfortunately it appears that because I created it with 1 disk there are no spare slots in the array so it does nothing.

Does anyone have any suggestions for what I can do? Reinstalling would be tricky :)

graid list shows:
Geom name: Intel-a795fa6b
State: OPTIMAL
Metadata: Intel
Providers:
1. Name: raid/r0
   Mediasize: 6001175121920 (5.5T)
   Sectorsize: 512
   Stripesize: 4096
   Stripeoffset: 0

   Subdisks: ada0 (ACTIVE)
   Dirty: Yes
   State: OPTIMAL
   Strip: 131072
   Components: 1
   Transformation: CONCAT
   RAIDLevel: RAID1
   Label: r0
   descr: Intel RAID1 volume
Consumers:

   Stripeoffset: 0
   Mode: r1w1e1
   ReadErrors: 0
   Subdisks: r0(r0):0@0
   State: ACTIVE (ACTIVE)

Whereas on other systems it says ‘Components: 2’ and ’Transformation: RAID1’.
