lvm2/test/shell/lvconvert-repair-raid.sh
Heinz Mauelshagen 55eaabd118 lvreduce/lvresize: add ability to reduce the size of a RaidLV
- support shrinking of raid0/1/4/5/6/10 LVs
- enhance lvresize-raid.sh tests: add raid0* and raid10
- fix have_raid4 in aux.sh to allow lv_resize-raid.sh
  and other scripts to test raid4
