Hi, My kernels are running: 3.8.11-200.fc18.x86_64 and 3.8.9-200.fc18.x86_64 My cephx settings are below auth cluster required = cephx auth service required = cephx auth client required = cephx I will be working on my test cluster later this week and will try to reproduce and will file a bug then.

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 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? Not currently. You can do this yourself with 'timeout 120 ...' with any recent coreutils.
