For a 2 node setup, you cant reliably use glusterfs for
master-master.<br>
<br>
DRDB is designed for a 2node cluster<br>
<br>
If you still want to use glusterfs, Create 2 sets of replicated
slaves with 6 brocks each. Each node has its own master and its
slave is replicated to the other server. This provides a backup.
Reads are local, writes are replicated and non realtime, this allows
you to have minmal network load.<br>
<br>
Adding a 3rd node to gluster fs is pretty easy.<br>
<br>
Ceph usually works better for VM;s and reducing IO.<br>

<div>I'm playing around with GlusterFS and have a few questions.
Have got a test setup running on a 2 node cluster (using
external USB Drives!) that works surprisingly well :) and I
must say it was very easy to setup.<br>

1. I wanted to implement a distributed/replicated file system.
Is GlusterFS the best choice for a 2 node system? Would it be
easy to add a third node later?<br>

<div>2. When launching a VM off Node 1 or Node 2, is it
accessing the local hard disk directly, or does it all go
through a network share? Our network is only 1GB and it
would be nice to take some of the load off it.<br>
<br>

Should I be asking these question on the forum rather than
the list?<br>

Thanks,<br>
