I would try the ceph pg repair. If you see the pg go into deep scrubbing, then back to inconsistent you probably have a bad drive. Find which of the drives in the pg are bad (pg query or go to the host and look through dmesg). Take that osd offline and mark it out. Once backfill is complete, it should clear up.On Sat, May 18, 2019, 6:05 PM Jorge Garcia <jgarcia@xxxxxxxxxxxx> wrote:We are testing a ceph cluster mostly using cephfs. We are using an erasure-code pool, and have been loading it up with data. Recently, we got a HEALTH_ERR response when we were querying the ceph status. We stopped all activity to the filesystem, and waited to see if the error would go away. It didn't. Then we tried a couple of suggestions from the internet (ceph pg repair, ceph pg scrub, ceph pg deep-scrub) to no avail. I'm not sure how to find out more information about what the problem is, and how to repair the filesystem to bring it back to normal health. Any suggestions?_______________________________________________Current status:# ceph -s
