Linux kernel version is plain 2.6.38.7 everywhere and the ceph > setup is fairly simple: 6 cosds, one cmon and one cmds. I created a new bug (http://tracker.newdream.net/issues/1110) for this. Can you generate an mds log for this and attach it to the bug? debug mds = 20 debug ms = 1 in the [mds] section and restart, or if the cluster is already up just ceph mds tell 0 injectargs '--debug-mds 20 --debug-ms 1' and then reproduce the problem. Should be at /var/log/ceph/mds.a.log or similar.
