I restarted the mons first, and as expected, they did not join a quorum with the 0.61.7 mons, but after all of the mons were restarted, there was no problem any more. One of my three osds would not come back online after the upgrade, but that is probably just this btrfs bug again: https://bugzilla.kernel.org/show_bug.cgi?id=60603 I will restart the machine tomorrow and see if it comes back. There was one qemu client running at the time of the update doing active IO, and apart from a temporary dip in performance, it was not affected. The whole thing was on Fedora 18, using Kernel 3.9.10-200.fc18.x86_64 and the repository under http://eu.ceph.com/rpm-testing/fc18/x86_64/, and btrfs as the OSD filesystem.
