(In fact this was a result of the call we had opened with RedHat). I'd love to have a working filesystem for ceph, but the xattr issue with ext4 really scares me. That's why I'm still wrestling with btrfs. On the first day after I rebooted the OSDs btrfs performance is really great. We can get up to 700 MB/s (over 10 Gigabit-Ethernet) inside a virtual machine, I haven't reached this with ext4.
