I have recently built a ceph cluster with the following nodes:
2011-04-08 11:54:08.038841 pg v3661: 264 pgs: 264 active+clean+degraded; 9079 MB data, 9234 MB used, 811 GB / 820 GB avail; 2319/4638 degraded (50.000%)
2011-04-08 11:54:08.039492 mds e17: 2/2/2 up {0=up:active,1=up:active}
2011-04-08 11:54:08.039529 osd e18: 4 osds: 4 up, 4 in
2011-04-08 11:54:08.039592 log 2011-04-08 10:08:09.135994 mds0 10.6.1.90:6800/16761 4 : [INF] closing stale session client4142 10.6.1.62:0/667143763 after 304.524869
2011-04-08 11:54:08.039673 mon e1: 1 mons at {0=10.6.1.90:6789/0}
I have a few files in the cluster (not much data) but have noticed from the beginning of the build (after the 2 osd) that some of my PGs are degraded.
How do I fix this and is there a tool/command to assist in determining what PGs are degraded?
Ceph -v is as follows:
ceph version 0.26 (commit:9981ff90968398da43c63106694d661f5e3d07d5)
I appreciate the help.
