If these tests are OK, I think we could make backported packages and test it again? for change from a stable relase: In my solution, I make sure the other ceph nodes and OSD processes are alive. Upgrade only one node in the same time, because it will make some osd down for a while due to removing ceph with libgoogle-perftools0. In this stage, we need to remove libgoogle-perftools0 and install libgoogle-perftools4 and its releated package. After that, install a new ceph package and OSDs will resume working normally.
