Well, I still don't see anywhere there is a documented definition that says "(NFS) fsid _is_ based on major/minor number". The man page describes it as "the filesystem identification portion of the file
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.

On the other hand, arguments like these are kind of silly. The important thing is to advocate and make sure people know how to use "fsid" in a clustered environment.
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,
Klaus
