Add to commits87117c2b25and0b8bf73a63to avoid refreshing two times altogether, thus avoiding issues related to clustered, remotely activated RaidLV. Avoid need to repeat "lvchange --refresh RaidLV" two times as a workaround to refresh a RaidLV. Fix handles removal of temporary *-missing-* devices created for any missing segments in RAID SubLVs during activation. Because the kernel dm-raid target isn't able to handle transiently failing devices properly we need "[dm-devel][PATCH] dm raid: fix transient device failure processing" as well. test: add lvchange-raid-transient-failures.sh and enhance lvconvert-raid.sh Resolves: rhbz1025322 Related: rhbz1265191 Related: rhbz1399844 Related: rhbz1404425
