Hi Ivan, Thanks for the info.
Will you clarify what I should be looking for in my bridge set up? It's fairly standard other then setting the MTU to 9000. The host/storage devices are using hardware RAID5. And all hypervisors are capable of mounting any of the NFS shares. Will you give me some detail on what you mean when you say using native RAID is a bad idea? Why is that and what is the recommended way to set up?

Management server doesn't care about systemvm. The only unit which cares - ssvm and hypervisor. Also, if you are using naive RAID/NFS within one cluster when any HV can mount any storage (mesh) it's extremely bad idea. You will get s lot of reboots if any of node meets outage. If you have DRBD or Gluster, then, it's fine. пт, 10 мая 2019 г., 6:32 Richard Persaud <richard.pers...@macys.com<mailto:richard.pers...@macys.com>>: > Hello, > > Our setup: > 4.11 on Ubuntu 16.04 LTS.
