Hello,
i have a question:
we have 2 datacenter - they are connected with 2 cables.
Last week we had an failure - both cables were "down" at once.
So we had on datacenter 1 - 2 hosts ok and 2 hosts disconnected -- the same on the other side.
And -> we have a lot of disconnected VMs on the both sides.
We have an synchronized storage between the two datacenter, so the VMs on each side could run.
The problem was, that i had to shutdown all machines on side 2, remove the disconnected hosts on side 1,
re register the VMs etc..
How can i prevent this ? is there any possibility to say:
datacenter 1 and his hosts are the "master" - if datacenter 2 fails (the hosts, network etc) shutdown all machines on datacenter 2
and start them in datacenter 1 ?
Thank you
