How to add a Gluster storage domain on hyper-converged?

Do you have 2 bricks on each node for the engine volume?

Use host -> use any of the hosts. path -> <host1>:/data Enter mount options -> backup-volfile-servers=<host2>:<host3> In 3.6, I think the mount options are automatically appended with backup-volfile-servers. But providing this info here will also work. The bakup-volfile-servers help in accessing the gluster volume when the host1 that was used to mount the volume goes down, and any of the other hosts needs to remount the gluster volume
I know this isnt officially supported yet, but if I can get it to work somehow, thatd be great :) Its a non-production (PoC) setup, so the cost of failure should be low... That said, I dont want to trash my rig and have to redo the whole thing all over ;)

Which version of glusterfs are you using? If you're trying this out for a POC, we recommend that you enable sharding on the gluster volumes (available from glusterfs 3.7.6 - http://gluster.readthedocs.org/en/release-3.7.0/Features/shard/). This will ensure that when self-heal happens on the gluster volume, the process does not hog CPU and completes relatively faster.
Thanks,
Will
