[ovirt-users] [Ovirt 4.1] Hosted engine with glusterfs (2 node)

Hi, I was trying to setup hosted engine on 2 host machine but it not allowing to setup hosted engine on 2 node gluster file system. I have also modified vdsm.com to allow 2 replica count. But latter I found in code it is hard coded to 3 as shown below: ------------------- ------------------------------- ------------------------------ --------------- src/plugins/gr-he-setup/storage/nfs.py if* replicaCount != '3'*: raise RuntimeError( _( 'GlusterFS Volume is not using replica 3' ) ) ------------------- ------------------------------- ------------------------------ --------------- Can I get to know the reason to hard coded to 3 ? from online I got to know that split brain issue not get resolve automatically using 2 node gluster setup. But please let me know more (why 3 ? why not 2 or 4 ?) If I am missing something please let me know. Also want to understand, can quorum can solve 2 node gluster issue (split-brain) ? Thanks, ~Rohit
