NFS via autofs:
Using autofs to (un)mount NFS, the 'autounmountd' does
not remove entries from /var/db/mounttab (on client) and
/var/db/mountdtab (on nfs-server) when client
disconnects after timeout.
Then running 'mount' on the client shows nfs filesystem is no longer
But looking at 'showmount' on the server, shows client still connected
even if it isn't.
- map type makes no difference
- mount options not changed from default
no problem though using "mount -t nfs ..." and "umount"
Then those entries are removed when unmounted.
Accessing the same nfs-server from a Fedora 26 or Debian 8
client via autofs (same autofs config as on FreeBSD) then the
entry on the server in /var/db/mountdtab is removed when client
This problem has existed since 10.3.
Also new setup server/client from scratch shows same
