At the very least, you should have an arbiter volume (introduced in Gluster 3.7) on a separate physical node.

Running Proxmox (Debian Wheezy) so limited to 3.6, however I do have a third peer node for voting purposes.

 

I don't think 4 GB is enough RAM, especially if you have a large L2ARC

Learned my lesson with earlier zfs setups :)  1GB ZIL, 10GB L2ARC.


You should also count the number of spindles you have and have it not exceed the number of VM's  you're running much to get decent disk IO performance. 

New one to me, did you mean the reverse? Number of VM's should not exceed the spindles?

Sorry, yes the reverse.
 



thanks,
