Subject: [PATCH 08/12] raid: add messages to lvs command output in case
RaidLVs require a refresh
If a RaidLV mapping is required to be refreshed as a result of temporarily failed
and recurred RAID leg device (pairs) caused by writes to the LV during failure,
the requirement is reported by volume health character r' in position 9 of the
LV's attribute field (see 'man lvs' about additional volume health characters).
As this character can be overlooked, this patch adds messages to the top
of the lvs command output informing the user explicitely about the fact.
(cherry picked from commit b69f73b13ee55ef3feb7427c6dc099dc3472d9fc)
