I could not tell you out of memory where it is defined, too bad it's not in
the man page: Should be enhanced!
Definitly the default for fsid is based on major/minor number, as long as you
don't have a fsid option in you're exports file.

Not only in clustered environment. It is necessary to use fsid in an LVM
environment. I learned this also the hard way, I always wondered about stale
handles on clients after server reboots and reexports, until I learned that
lvm minor numbers can change, and until I discovered fsid.
But be careful! There is nothing that prevents you from using same fsid for
different exports.
Sincerly,
