It just uses LVM to create a bunch of LVs. It doesn't actually create
separate partitions on the block devices. You can run the command and it
will give you a previe

The way I did this was to use:
ceph-volume lvm batch /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/sde
/dev/sdf etc
Where you just list all of the block devices
did the partitioning look like?

Where you just list all of the block devices you want to use in a group. It
will automatically determine which devices are SSD and then automatically
partition it for you and share it am
You can loop over the creation of LVs on the SSD of a fixed size, then
loop over creating OSDs assigned to each of them. That is what we did,
it wasn't bad.

I have a bunch of hard drives I want to use as OSDs, with ceph nautilus.
ceph-volume lvm create makes straight raw dev usage relatively easy, since you
can just do
ceph-volume lvm create --data /dev/sdc
or whatever.
Its nice that it takes care of all the LVM jiggerypokery automatically.
but..
