Description
Sorry if there are "feature", not a "bug", but from users point of view there are annoying bug.
I have 3 node, HEALTH_OK, pool "rbd" with 2/1 size (size=2 min_size=1), want to change to 3/2. OK:- ceph osd pool set rbd size 3
... - ceph healt
HEALTH_WARN 746 pgs backfill; 51 pgs backfilling; 797 pgs degraded; 797 pgs stuck unclean; recovery 290939/1473231 degraded (19.748%); recovering 17 o/s, 69066KB/s
On my look, in pure theory, this situation must have NO stuck pages: I have min_size=1, size changed from 2 to 3, all data have 2 OK replicas...
IMHO it can produce stuck pages in many other cases, but this is most clean to understand.

'stuck' just means it has been in this state for more than a few minutes.. in this case, recovery is just taking a while, it looks like!
