GlusterFS is on the list...

Now I just playing with Ceph...

And I wonder if Ceph has some minimum size of disk...
I tried create one OSD with a 2 GB disk and doesn't work:

ceph-disk -v prepare --zap-disk --fs-type xfs --cluster ceph --cluster-uuid
9171be6a-6a47-4f39-bf8d-0442c75e4bdd /dev/sdc
DEBUG:ceph-disk:Zapping partition table on /dev/sdc
Creating new GPT entries.
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.
The operation has completed successfully.

I think I need more than 2 GB....
