Re: unable to repair PG

Hi,

I've stopped OSD.16, removed the PG from the local filesystem and started the OSD again. After ceph rebuilt the PG in the removed OSD I ran a deep-scrub and the PG is still inconsistent.

I'm running out of ideas on trying to solve this. Does this mean that all copies of the object should also be inconsistent? Should I just try to figure which object/bucket this belongs to and delete it/copy it again to the ceph cluster?

Also, do you know what the error message means? is it just some sort of metadata for this object that isn't correct, not the object itself?

Hi,

In the last few days this PG (pool is .rgw.buckets) has been in error after running the scrub process.

After getting the error, and trying to see what may be the issue (and finding none), I've just issued a ceph repair followed by a ceph deep-scrub. However it doesn't seem to have fixed the issue and it still remains.

The relevant log from the OSD is as follows.
