Hi all, installing an OSD on an LVM volume seems not to be supported by the current 'ceph-deploy osd' or 'ceph-disk prepare' tools. Therefore I tried to do it manually as suggested here: http://eturnerx.blogspot.de/2014/08/how-i-added-my-lvm-volumes-as-osds-in.html TL;DR, the process is: - create volume - format volume - mount volume to /var/lib/ceph/ceph-$OSD_ID - create symlink from /var/lib/ceph/ceph-$OSD_ID/journal to journal volume This seems to work, however, the disks are not listed by 'ceph-disk list'. There seem to be other approaches which involve creating a partition table on the LVM volumes, as described here, for example: http://dachary.org/?p=2548 which seem to be a bit more involved and I haven't tried. Is there a recommended way of running an OSD on top of a LVM volume? What are the pros and cons of the approaches? Is there a downside to the disks not being listed by 'ceph-disk list' as per the first approach? Thanks in advance for any enlightenment!
