My system comprises 2 x 3TB hard drives, each partitioned into a 4GB
swap, a 36GB /, and the rest for /home. / and /home are (were) then
assembled into btrfs raid1 arrays, with both metadata and data being
mirrored.
I then installed the wrong graphics drivers for my nVidia card,
resulting in an unbootable system. The only way out was to reinstall
the system (openSUSE 13.2), but it only used a single drive, resulting
in the following setup:
:~ # btrfs fi sh

I would like some advice on how to safely delete the contents of
/dev/sdg2, and then add it to /dev/sdf2 to make a new raid1 array. I
know how to do the second step,
mkfs.btrfs -m raid1 -d raid1 /dev/sdf2 /dev/sdg2
(or would that destroy the data on /dev/sdf2 ?)
and I could delete the contents of the partition, but in between these
two steps I'm supposing I need to disassemble one raid1 array and then
put it together again.
Or maybe I'm making this seem harder than it really is?
