[CentOS] stale file handle issue

I've run out of ideas on this.... A CentOS 6 box serving nfs: two
directories separately: /this/partition/dir0 and /this/partition/dir1.
Everything looks good on it. On the servers it's exporting to - two are
CentOS 6, one's CentOS 7, they all automount
/net/server/this/partition/dir0... but no matter what I've done,
restarting autofs and nfslock, umounted things... but with autofs off,
even when I manually mount it to /mnt, I get stale file handle.

The two dirs are owned by root, but one's got a different group. Selinux
settings are the same.

Clues for the poor?
