Milan Broz bdc7574fd5 If pvmove fails activating mirror volume, try restore to previous state.
pvmove now keep suspended devices if temporary mirror creation fails.

We can try to restore previous state if it is first attempt to activate
pvmove (code basically run the same code as --abort automatically).
