Yes, that was my bug; I mounted them now, and everything is fine
again.
Apparently the cluster remembers which node owns which OSD, and where
it expects this OSD to be mounted, but does not remember the device.
I had created my OSDs initially with
ceph-deploy osd prepare node:/dev/sdX
and started them with
ceph-deploy osd activate node:/dev/sdX
So I assume I should manually extend my fstabs to mount these
filesystems on /var/lib/ceph/osd/ceph-Y. My (wrong) assumption was
that the osd filesystem is automatically mounted by /etc/init.d/ceph
start osd.
The filesystem should be mounted automatically via some udev triggers when the device appears, assuming everything was set up correctly. But maybe the disks didn't get the proper type set or something.
