Hi：
I had met an assert problem like
bug16279(http://tracker.ceph.com/issues/16279) when testing pull out disk and
insert, ceph version 10.2.5，assert(objiter->second->version >
last_divergent_update)
according to osd log，I think this maybe due to (log.head !=
*log.log.rbegin.version.version
st, so the
consistent one(osd who has shorter pg log,but last_update is normal) may become
the auth log,
other osd use 'this auth log' would lead to pg inconsistent if scrub this
pg,isn’t it?
