There are a number of bugs that have been fixed since Linux 3.4, and the fixes have not made it into the 3.4.y stable releases. I just sent an announcement about the Ceph stable branch that's available in the Ceph git repository. If possible I would recommend you try using that for 3.4 testing. The branch is here: http://github.com/ceph/ceph-client/tree/linux-3.4.4-ceph If you do have troubles I would very much like to hear about it. And if you don't run into the problems you've been seeing that would be good to know as well. -Alex > I'll launch realistic load on our ceph volume this week end (bacula > backups).
