I'm running into this exact same situation. I'm running 12.2.2 and I have an EC PG with a scrub error. It has the same output for  rados list-inconsistent-obj as mentioned before. This is the  full health detail. This is the  excerpt from the log from the deep-scrub that marked the PG inconsistent. The scrub happened when the PG was starting up after using ceph-objectstore-tool to split its filestore subfolders. This is using a script that I've used for months without any side effects.
I have tried quite a few things to get this PG to deep-scrub or repair, but to no avail. It will not do anything. I have set every osd's osd_max_scrubs to 0 in the cluster, waited for all scrubbing and deep scrubbing to finish, then increased the 11 OSDs for this PG to 1 before issuing a deep-scrub. And it will sit there for over an hour without deep-scrubbing. My current testing of this is to set all osds to 1, increase all of the osds for this PG to 4, and then issue the repair... but similarly nothing happens. Each time I issue the deep-scrub or repair, the output correctly says 'instructing pg 145.2e3 on osd.234 to repair', but nothing shows up in the log for the OSD and the PG state stays 'active+clean+inconsistent'. My next step, unless anyone has a better idea, is to find the exact copy of the PG with the missing object, use object-store-tool to back up that copy of the PG and remove it. Then starting the OSD back up should backfill the full copy of the PG and be healthy again.  $ rados list-inconsistent-obj 145.2e3 No scrub information available for pg 145.2e3 error 2: (2) No such file or directory  $ ceph health detail HEALTH_ERR 1 scrub errors; Possible data damage: 1 pg inconsistent OSD_SCRUB_ERRORS 1 scrub errors PG_DAMAGED Possible data damage: 1 pg inconsistent pg 145.2e3 is active+clean+inconsistent, acting [234,132,33,331,278,217,55,358,79,3,24]  2018-04-04 15:24:53.603380 7f54d1820700 0 log_channel(cluster) log [DBG] : 145.2e3 deep-scrub starts 2018-04-04 17:32:37.916853 7f54d1820700 -1 log_channel(cluster) log [ERR] : 145.2e3s0 deep-scrub 1 missing, 0 inconsistent objects 2018-04-04 17:32:37.916865 7f54d1820700 -1 log_channel(cluster) log [ERR] : 145.2e3 deep-scrub 1 errors On Mon, Apr 2, 2018 at 4:51 PM Michael Sudnick <michael.sudn...@gmail.com> wrote: > Hi Kjetil, > > I've tried to get the pg scrubbing/deep scrubbing and nothing seems to be > happening.
