Re: [ovirt-users] glusterFS is not independent?

2017-11-09 Thread Johan Bernhardsson
Gluster would be to overcomplicate this if you only want local storage
on both to be reachable over the network.
Simplest way is to setup an nf server on both nodes and create a
storage domain for each.
Gluster is a way to secure your data and replicate them over several
nodes. so that if one node goes down or explodes you always have the
data replicated to other nodes. Running a single brick gluster volume
is not recomended.

For it to work you need to have the bricks in replicate. Of brick on
each server. 
If you only have two nodes. The quoum will be to low so it will set the
gluster to failsafe mode until the other brick comes online. 
For it to work properly you need three nodes with one brick or two
nodes and a third node acting as an arbiter.
