Hi
I am interested in this too!
We have two Ceph arrays too and we have found that we get these same
errors about once a fortnight on each array.
One array is in a colo site and the other in the office. Both arrays
have 3 replications, version 0.80.1. The osd's are running on zfs
which show no errors but we seem to be getting these placement group
errors. The errors seem to be happening a bit too often for comfort.
Ceph is great product but I am not convinced enough for production yet.
Is anyone else getting these issues? I would like to figure out if is a
real Ceph issue or our environment.
Cheers
Peter

Hi all,
after coming back from a long weekend, I found my production cluster in
an error state, mentioning 6 scrub errors and 6 pg's in
active+clean+inconsistent state.
Strange is, that my Prelive-Cluster, running on different Hardware, are
also showing 1 scrub error and 1 inconsisten pg...
pg dump shows that 6 different OSD's are affected. I will check again
for some Hardware Errors, but since the hardware is quite new, and none
of our monitoring checks found disk errors, I'm not sure about it.
What can be the cause of such a problem? And, what is also interesting,
how to recover from it? :)
Regards,
Christian
