I did read through that and i see you can do HA node option.
The document talks about for high availablity, that would mean that the
second node would sit idle.
I am wondering if xcat allows multiple management nodes to be used who can
submit commands to the nodes at the same time.
I believe multiple management nodes will create race conditions if issuing
commands on the nodes at the same time.
In the service node concept, do you put the scheduler on each service node
for it to be able to submit jobs to the resources.
Does xcat recommend having more than 2 management nodes because i dont see
it in any architecture diagram?
Thanks
