Testing could be quite easy: reset-brick start, then delete&re-create
partition/fs/etc., reset-brick commit force - and then watch.
We only have 1 big volume over all bricks. Details:
Volume Name: shared
Number of Bricks: 4 x 3 = 12
Didn't think about creating more volumes (in order to split data),
e.g. 4 volumes with 3*10TB each, or 2 volumes with 6*10TB each.
Just curious: after splitting into 2 or more volumes - would that make
the volume with the healthy/non-restoring disks better accessable? And
only the volume with the once faulty and now restoring disk would be
in a "bad mood"?

Yeah, would be interested in how the glusterfs professionsals deal
with faulty disks, especially when these are as big as our ones.
