Joseph, I suspect the same...I was just wondering if it was supposed to be supported using ceph-deploy since CERN had it in their setup. I was able to use '/dev/disk/by-id', although when I list out the osd mount points it still shows sdb,sdc, etc: oot@hqosd1:/dev/disk/by-id# df -h Filesystem Size Used Avail Use% Mounted on /dev/sdb1 3.7T 36M 3.7T 1% /var/lib/ceph/osd/ceph-0 /dev/sdc1 3.7T 36M 3.7T 1% /var/lib/ceph/osd/ceph-1 I guess I was excepting the mount points to use those 'by-id' names instead....but maybe this is expected?
