I'm running my cluster(s) on Ubuntu 11.10. For the OSD's you don't have to run the latest kernel, but if you decide to use btrfs it could be a good idea to use a new kernel. btrfs is still under development, it get's better with every kernel. I think the main test systems of the dev's are running Debian, so that might be a good choice. Debian packages are available on the Ceph website or can easily be build from source. When you want to use the kernel client (CephFS / POSIX filesystem) I recommend using a recent kernel on the client, same story was with btrfs.
