Hi, from the beginning, I have never seen the command "ceph -w" works on my cluster. The only thing I obtain, is the "ceph status" then one very old error message : root! keron:~# ceph -w health HEALTH_WARN 35 pgs degraded; 495 pgs stuck unclean; recovery 354282/9298732 degraded (3.810%); 1 near full osd(s); 1/45 in osds are down monmap e7: 5 mons at {a=10.0.0.1:6789/0,b=10.0.0.2:6789/0,c=10.0.0.5:6789/0,d=10.0.0.6:6789/0,e=10.0.0.3:6789/0}, election epoch 2016, quorum 0,1,2,3,4 a,b,c,d,e osdmap e44276: 46 osds: 44 up, 45 in pgmap v9895366: 7824 pgs: 7328 active+clean, 460 active+remapped, 35 active+degraded, 1 active+clean+scrubbing; 5118 GB data, 16390 GB used, 19773 GB / 36164 GB avail; 73633KB/s wr, 421op/s; 354282/9298732 degraded (3.810%) mdsmap e1: 0/0/1 up 2012-12-10 11:45:35.407734 unknown.0 [INF] mkfs de035250-323d-4cf6-8c4b-cf0faf6296b1 (yes, one OSD is down, and an other one is near full, but that's a different problem) I tried to read the code of ceph, without any success. I also tried to enable some debugging information, but I don't see any change in the output of "ceph -w". Any idea how can I fix that ? I use ceph 0.56.4 on Debian Squeeze (rebuilt), with Linux >= 3.6. thanks in advance, Olivier B. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
