Try mounting > them and seeing what blocked the mount 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.
