Subject: osd: based INCONSISTENT pg state on persistent scrub errors
X-Git-Tag: v0.57~200
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=2baf1253eed630a7c4ae4cb43aab6475efd82425;p=ceph.git

osd: based INCONSISTENT pg state on persistent scrub errors

This makes the state persistent across PG peering and OSD restarts.

This has the side-effect that, on recovery, we rescrub any PGs marked
inconsistent.  This is new behavior!
