      Description

      As a shortcut in developing HA, we elected not to deal with the case of storage directory recovery while HA is enabled. But there are many cases where we can and should handle it. For example, if the user configures two local dirs and one shared dir, but one of the local dirs is empty at startup, we should be able to re-format the empty dir from the other local dir.

        Hi Todd Lipcon
        Is this still a issue for 2.x? If so, would you mind retarget it to 2.5?
        If not, could we close it?

        This is still valid. Let's target for 3.0.0 instead of resolving it.
