Ilya, Here is the steps.. 1. You have a cluster (3 nodes) and replication is 3 2. map krbd image to a client. 3. Reboot or stop ceph services on one or more nodes 4. The client with krbd mapped module crashes Also, if we try to reboot the clients without unmapping the clients, client nodes goes into a loop and requires hard boot. But, we found this issue is fixed in later version of rbd. We are using inbox rbd coming with Ubuntu 14.04 LTS. Let me know if you need further details.

Is this fix backported to any 14.04 stable LTS kernel ? I don't recall anything like that or at least phrased that way. Can you give more details - crash traces at least?
