I just responded to this on the thread "Strange remap on host failure". I think that response covers your question.

Hello,
can someone give me some directions on how the ceph recovery works?
Let's suppose we have a ceph cluster with several nodes grouped in 3 racks (2 nodes/rack). The crush map is configured to distribute PGs on OSDs from different racks.
What happens if a node fails? Where can I read a description of the actions performed by the ceph cluster in case of a node failure?
Kind regards,
Laszlo
