Bug #18749
closedOSD: allow EC PGs to do recovery below min_size
0%
Description
PG::choose_acting has a stanza which prevents EC PGs from peering if they are below min_size because, at the time, Sam was worried about committing to an update without having min_size OSDs present.
He says we ought to be able to disable this now that recovery below min_size works at all, but of course it will need stringent testing.

I think it would make sense to create a note on this recovery limitation in the documentation http://docs.ceph.com/docs/master/rados/operations/erasure-code/ and have it backported to luminous+mimic+nautilus ?
