Hi,
I'm trying to figure out how things are supposed to be done.
Suppose I'm running compute nodes using shared instance storage (via
NFS, for example).
Now suppose I have a network issue which isolates a compute node. I
evacuate the instances that were on that node, which causes them to
start running somewhere else.
Now we fix the network issue.
As far as I can tell, we now have two separate kvm instances, on two
different machines, both using the exact same virtual disk file. This
seems like a bad idea.
Am I missing something? Or do you need a STONITH device for compute
nodes to safely evacuate instances from a failed compute node?
Chris
