Re: inconsistent pg on erasure coded pool

This says it's actually missing one object, and a repair won't fix that (if it could, the object wouldn't be missing!). There should be more details somewhere in the logs about which object.

Hi,

We have some inconsistency / scrub error on a Erasure coded pool, that I
can't seem to solve.

[root@osd008 ~]# ceph health detail
HEALTH_ERR 1 pgs inconsistent; 1 scrub errors
pg 5.144 is active+clean+inconsistent, acting
[81,119,148,115,142,100,25,63,48,11,43]
1 scrub errors

In the log files, it seems there is 1 missing shard:

/var/log/ceph/ceph-osd.81.log.2.gz:2017-10-02 23:49:11.940624

7f0a9d7e2700 -1 log_channel(cluster) log [ERR] : 5.144 deep-scrub 1 errors

I tried running ceph pg repair on the pg, but nothing changed. I also
tried starting a new deep-scrub on the  osd 81 (ceph osd deep-scrub 81)
but I don't see any deep-scrub starting at the osd.

How can we solve this ?

Thank you!


Kenneth
