Hi All, I have had an issue recently while working on my ceph clusters. The following issue seems to be true on bobtail and cuttlefish. I have two production clusters in two different data centers and a test cluster. We are using ceph to run virtual machines. I use rbd as block devices for sanlock. I am running Fedora 18. I have been moving monitors around and in the process I got the cluster out of quorum, so ceph stopped responding. During this time I decided to reboot a ceph node that performs an rbd map during startup. The system boots ok but the service script that is performing the rbd map doesn't finish and eventually the system will OOPS and then finally panic. I was able to disable the rbd map during boot and finally got the cluster back in quorum and everything settled down nicely. Question, has anyone seen this behavior of crashing/panic? I have seen this happen on both of my production clusters. Secondly, the ceph command hangs when the cluster is out of quorum, is there a timeout available?
