HA does not mean multiple running instances of the same service. It means if the service is gone, it will automatically be restored on a working server. Hosted engine has HA built in, without the need to run multiple engines. If the server where the engine is running goes down, the engine gets

Two things off the top of my head after skimming the given details: 1. iSCSI will work better without the bond. It already uses multipath, so all you need is to separate the portal IPs/subnets and provide separate IPs/subnets to the iSCSI dedicated NICs, as is the recommended way here:

If the model can be shared between two hosts (I remember the old PVs having this option as an alternative to a split backplane) then potentially you should be able to detect the shared volume with multipath and oVirt should be able to pick it up as FC storage On Mon, Mar 21, 2016 at 7:34 AM,
