This is because ceph-volume can accept both LVs or GPT partitions for block.db
Another way around this, that doesn't require you to create the LVs is
to use the `batch` sub-command, that will automatically
detect your HDD and put data on it, and detect the SSD and create the
block.db LVs. The command could look something like:
ceph-volume lvm batch --bluestore /dev/sda /dev/sdb /dev/sdc /dev/sdd
/dev/nvme0n1
Would create 4 OSDs, place data on: sda, sdb, sdc, and sdd. And create
4 block.db LVs on nvme0n1
