Description

I have relaxed the check on LV name restrictions for both --repair and (relevant in this bug) --splitmirror. The LV to split can be a special (i.e. _cdata, _cmeta and so on), as long as the --name given is a regular name. The fix is upstream in b66f16fd63014c958d65ab37df4b72f1566176d3.
