Looking at the logs I finally found the issue: when I said that there were no changes in network topology, I was mistaken. I removed an unused (or at least I thought so) network board from each server. These servers had 2 network boards that I installed and configured so I would have a "public network" and a "cluster network". That was when I was first installing the ceph cluster. After having some problems with this set up I was advised by members of this list to not use this dual network setup as it could make debugging much more difficult. I followed this advice, or at least tried to. To make a long story short, ceph was still trying to use the second network for some OSDs. With a "ceph config rm global cluster_network" and a general restart of the cluster, everything started working again. Thanks for the help and sorry for the confusion.
