I'll caution that while the OSD will be correctly ID'd you might have trouble if you've got your journals on different disks. Running Ubuntu 13.10 with ceph 0.72.2 I had my journal disk swap places with another drive on reboot and all associated OSDs failed to start. In the future I'll have ceph-deploy use /dev/disk/by-partuuid for the journals instead of /dev/sd*#. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
