I'm a bit confused after reading this. Just to make things clear. Would bluestore be put on top of a LVM volume (in an ideal world)? Has bluestore in Ceph luminious support for LVM? I.e. is there code in bluestore to support LVM? Or is it _just_ support of `ceph-volume lvm` for bluestore? > --- New clusters --- > The `ceph-volume lvm` deployment is straightforward (currently > supported in ceph-ansible), but there isn't support for plain disks > (with partitions) currently, like there is with ceph-disk. > > Is there a pressing interest in supporting plain disks with > partitions? Or only supporting LVM-based OSDs fine? We're still in a green field situation. Users with an installed base will have to comment on this. If the assumption that bluestore would be put on top of LVM is true, it would make things simpler (in our own Ceph ansible playbook). Gr.
