Dear Cephalopodians, I found the messages: 2019-05-30 16:08:51.656363 [ERR] Error -5 reading object 2:0979ae43:::10002954ea6.0000007c:head 2019-05-30 16:08:51.760660 [WRN] Error(s) ignored for 2:0979ae43:::10002954ea6.0000007c:head enough copies available just now in our logs (Mimic 13.2.5). However, everything stayed HEALTH_OK and seems fine. Pool 2 is an EC pool containing CephFS. Up to now I've never had to delve into the depths of RADOS, so I have some questions. If there are docs and I missed them, just redirect me :-). - How do I find the OSDs / PG for that object (is the PG contained in the name?) I'd love to check SMART in more detail and deep-scrub that PG to see if this was just a hiccup, or a permanent error. - Is there also a way to map the object name to a CephFS file object and vice-versa? In one direction (file / inode to object), it seems this approach should work: http://lists.ceph.com/pipermail/ceph-users-ceph.com/2015-October/005384.html - Should Ceph stay healthy in that case? Does it maybe even deep-scrub automatically, and only decide afterwards whether to stay healthy / whether repair is needed? Cheers and thanks, Oliver
