Here is another problem I've seen. Unfortunatly I do not have any debug output and it's not reproduceable. While removing an image with "rbd rm" I noticed that rbd stopped making progress. When I looked with "ceph -w" I saw a PG, that was in state "active+clean+scrubbing": 2011-10-25 14:01:34.198961 pg v1215175: 2776 pgs: 2775 active+clean, 1 active+clean+scrubbing; 3000 GB data, 1658 GB used, 56737 GB / 59615 GB avail This state didn't change for half an hour, so I decided to look which OSD is involved pg_stat objects mip degr unf kb bytes log disklog state v reported up acting last_scrub 2.163 773 0 0 0 3162113 3238002800 1917 1917 active+clean+scrubbing 2626'7909 2597'10775 [11,7] [11,7] 2613'7708 2011-10-24 11:54:39.890963 and I restared OSD 11. After that everything went back to normal - the "rbd rm" finished and scrubbing continued on other PGs. Doing a manual scrub on 2.163 is fine, too.
