Hi All, Earlier ceph on Debian Jessie was working. Jessie is running 3.16.7 . Now when I modprobe rbd , no /dev/rbd appear. # dmesg | grep -e rbd -e ceph [ 15.814423] Key type ceph registered [ 15.814461] libceph: loaded (mon/osd proto 15/24) [ 15.831092] rbd: loaded [ 22.084573] rbd: no image name provided [ 22.230176] rbd: no image name provided Some files appear under /sys ls /sys/devices/rbd power uevent ceph-fuse /mnt/cephfs just hangs. I haven't changed the ceph config, but possibly there were package updates. I did install a earlier Jessie kernel from a machine which is still working and rebooted. No luck. Any ideas of what to check next? Thanks, Chad. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
