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

[TranceWorldLogic .]

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
