-Till Ceph luminous, Filestore was used as storage type for Ceph OSDs. It can
-still be used and might give better performance in small setups, when backed by
-an NVMe SSD or similar.

-NOTE: In order to select a disk in the GUI, the disk needs to have a
-GPT footnoteref:[GPT] partition table. You can
-create this with `gdisk /dev/sd(x)`. If there is no GPT, you cannot select the
-disk as journal. Currently the journal size is fixed to 5 GB.

-If you want to use a dedicated SSD journal disk:
-
-[source,bash]
-----
-pveceph createosd /dev/sd[X] -journal_dev /dev/sd[Y] -bluestore 0
