[ovirt-users] Rebuilding my infra..

[carl langlois]

I should have say replica 3+arbiter when adding the 3rd host.

Yes i know that the documentation specified 3 hosts. But if i understand
this is to make sure the system is always reliable and that make sense. But
my questions is mainly is it possible to start with 2 nodes and had a 3rd
one later..when i had the budget. If i am not mistaking Gluster can work
with 2 nodes.
