Ceph is telling me that it can't find some data:
2014-04-07 11:15:09.901992 mon.0 [INF] pgmap v5436846: 2592 pgs: 2164
active+clean, 142 active+remapped+wait_backfill, 150
active+degraded+wait_backfill, 1 active+recovering+degraded, 2
active+degraded+backfilling, 133 active+degraded+remapped+wait_backfill;
15094 GB data, 28749 GB used, 30839 GB / 59588 GB avail;
3496837/37879443 objects degraded (9.231%); *1/18361235 unfound
(0.000%)*; 25900 kB/s, 26 objects/s recovering
querying all the PGs tells me that 11.483 has 1 missing object, named
.dir.us-west-1.51941060.1.
pg query says the recovery state is:
"might_have_unfound": [
{ "osd": 11,
"status": "querying"},
{ "osd": 13,
"status": "already probed"}],
Active OSDs for this PG are [3,13], so osd.13 is the 2ndry for this PG.
osd.11 does not have the data. I recently replaced osd.11, and this
data was unfound before the drive swap. So it looks like I have no
choice but to use mark_unfound_lost.
I have some concerns though. Pool 11 is .rgw.buckets. I assume from
the object's name, .dir.us-west-1 is related to replication. us-west-1
is the master zone, and these errors are occuring in the slave zone
(us-central-1).
What are the risks of using ceph pg {pgid} mark_unfound_lost revert on
that particular object? I'm comfortable losing objects in the slave, I
can re-upload them to the master zone. I just want to make sure I'm not
going to render the slave zone unusable.
Thanks for the help.
