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? mark
