Hi Simon, Thank you for responding back. I am currently running ACS 4.9 on an Ubuntu 14.04 VM. I have the three nodes, each having about 1TB of primary storage (NFS) and 1TB of secondary storage (NFS). I added each NFS share into ACS. All nodes are in a cluster.
Maybe I'm not understanding the setup or misconfigured something. I'm trying to setup an HA environment where if one node goes down, running an HA marked VM, the VM will start on another host. When I simulate a network disconnect or reboot of a host, all of the nodes go down. If you request more information, please let me know. Again, any help is greatly appreciated!
