[Gluster-users] High-availability with KVM?

With that setup, you lose quorum if you lose any one node.
Brick 1 replicates to brick 2, and brick 3 replicates to brick 4. If any
one of those goes down, quorum falls to <51%, which locks the brick under
the default settings.

If you've only got 4 servers to play with, I suggest you move to
replication 3 arbiter 1. Put the arbiter for servers 1 & 2 on server 3, and
the arbiter for servers 3 & 4 on server 1.
