Hi, I'm running a cluster with 12.2.1 and adding more OSDs to it. Everything is running version 12.2.1 and require_osd is set to luminous. one of the pools is replicated with size 2 min_size 1, and is seemingly blocking IO while recovering. I have no slow requests, looking at the output of "ceph osd perf" it seems brilliant (all numbers are lower than 10). clients are RBD (OpenStack VM in KVM) and using (mostly) 10.2.7. I've tagged those OSDs as out and the RBD just came back to life. I did have some objects degraded: 2018-01-10 18:23:52.081957 mon.mon0 mon.0 x.x.x.x:6789/0 410414 : cluster [WRN] Health check update: 9926354/49526500 objects misplaced (20.043%) (OBJECT_MISPLACED) 2018-01-10 18:23:52.081969 mon.mon0 mon.0 x.x.x.x:6789/0 410415 : cluster [WRN] Health check update: Degraded data redundancy: 5027/49526500 objects degraded (0.010%), 1761 pgs unclean, 27 pgs degraded (PG_DEGRADED) any thoughts as to what might be happening? I've run such operations many a times... thanks for all help, as I'm grasping as to figure out what's happening... _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
