but all services are up.

Im still looking at this, and it might not even be the hosts, gooan take a look at the network now too.

It sounds like you might have lost monitor quorum. When ceph -s hangs even though your monitors seem to be running, it usually means the client is stuck waiting for a monmap it can't get.

You can bypass the cluster entirely and query the monitor directly through its admin socket:
ceph daemon mon.$(hostname -s) mon_status
