Its for storage of VM disks, not OS but like filestorage.
I have done a similar setup with distributed replicated arbiter volumes, but i loose so
much storage space.
Each disk is 6TB, in a raid 5 it would be 66TB, with dispersed ~45TB, with D-R-A it was
around 28TB, quite a massive loss.
It was an replicated 3 arbiter 1 setup. When i did this i used LVM and set Arbiter volume
as a smaller disk, think it was 2TB
Like this:
