I haven't specifically tested it in this precise context, but in general
that's exactly what it does. We went to using autofs because we had a server
that was prone to crash. With autofs, as soon as that server came back up,
it got remounted. Very reliable for that.

When a server crashes the mount goes away. When you ask for a filesystem
with autofs, if it's not there, it tries to mount it. I don't see how it can
even know if you've switched which system has the IP and filesystem it's
trying to mount. I know for sure it works well in a setup with
DRBD/Heartbeat/NFS, so it ought to work as well for Gluster/UCARP/NFS. From
autofs's perspective, it's just NFS.
