Hello,
I have one Multi State resource and I want to permit it to start on one
node and then in the other.
In normal situation we will have two nodes starting at same time. With
constraints Heartbeat will decide the best node to run all resources.
But in another situation, We could have only one node starting. At this
moment we need to start all resources in this node.
How can I permit this situation ?
What's there to permit? I suppose that in this case there will be
only the master instance of the resource running. Or did I
misunderstand your question?
No, You understood my question but I can't achieve that with my config
file and I don't know why.
Do you know some tip ?
Thanks,
Dejan
I can't use globally-unique as an option of multi state. One option could
be "ordered" ?
I have attached my config file.
Could you have a look ?
Thank you!
