Hi all, We started running a EC pool based object store, set up with a 4+2 configuration, and we seem to be getting an almost constant report of inconsistent PGs during scrub operations. For example: root@rook-tools:/# ceph pg ls inconsistent PG_STAT OBJECTS MISSING_ON_PRIMARY DEGRADED MISPLACED UNFOUND BYTES LOG DISK_LOG STATE STATE_STAMP VERSION REPORTED UP UP_PRIMARY ACTING ACTING_PRIMARY LAST_SCRUB

We have been running the PG repair operation on them (e.g. ceph pg repair <pg num>), which clears the issue. Is this the correct way to resolve this issue? Is this a normal behavior for a Ceph cluster? If so, why doesn’t it attempt to repair itself automatically? Thanks for the help understanding Ceph, we are very new to it still! -Bryan Note: This email is for the confidential use of the named addressee(s) only and may contain proprietary, confidential, or privileged information and/or personal data.
