Activate storage during domain migration

Hi, I have a block storage which I only want to be mounted on a single node. I know that there are many possibilities for shared storage usage but I want to know if the following is possible (using the API). - Have a domain running on node-A - Initialize a migration for that domain to node-B - Run a hook or something just before the domain starts on node-B to:     - unmount storage on node-A     - mount/prepare storage on node-B Thanks and best regards, Etienne
