Hi, to have more meaningful names, I also prefer LVM for the db drive. Create the volume on OSD by hand too: vgcreate ceph-block-0 /dev/sda lvcreate -l 100%FREE -n block-0 ceph-block-0 DB Drive: vgcreate ceph-db-0 /dev/nvme0n1 lvcreate -L 50GB -n db-0 ceph-db-0 lvcreate -L 50GB -n db-1 ceph-db-0 ... ceph-volume lvm create --bluestore --data ceph-block-0/block-0 --block.db ceph-db-0/db-0 Unfortunately this is not ceph-disk, as requested in the original question. so long Thomas Am 22/10/2019 um 08:17 schrieb Ingo Schmidt: > Hi Frank > > We use such a setup on our nautilus cluster.
