RPC.UMNTALL(8)		  BSD System Manager's Manual		RPC.UMNTALL(8)

NAME
     rpc.umntall -- notify NFS servers about unmounted NFS file	systems

SYNOPSIS
     rpc.umntall [-e expire] [-h host] [-k] [-p	remotepath] [-v]

DESCRIPTION
     The rpc.umntall utility is	proposed in the	NFS RPC	specification; see NFS
     Version 3 Protocol	Specification, RFC 1813, Appendix I.  It uses remote
     procedure calls to	remove mount entries from /var/db/mountdtab on the re-
     mote NFS server.  It is called automatically without any parameters dur-
     ing startup and shutdown of the system.  This ensures that	showmount(8)
     does not display old and expired entries.	The rpc.umntall	utility	is
     only needed on client side, where mount_nfs(8) adds a mount entry with
     the current date to /var/db/mounttab, and umount(8) removes the entry
     again.  The rpc.umntall utility cares about all remaining entries in this
     table which result	from crashes or	unproper shutdowns.

     The options are as	follows:

     -e	expire	All entries which are not actually mounted or older than
		expire (seconds) are removed from /var/db/mounttab.  This may
		be the case for	DNS changes or long out	of service periods.
		Default	expire time is 86400 seconds (one day).

     -h	host	Only remove the	specific hostname.  Send a UMNTALL RPC to the
		NFS server.

     -k		Keep entries for existing NFS file systems.  Compare the NFS
		file systems from the mounttab against the kernel mountlist
		and do not send	the RPC	to existing mount entries.  Useful
		during startup of the system.  It may be possible that there
		are already mounted NFS	file systems, so calling RPC UMOUNT is
		not a good idea.  This is the case if the user has rebooted to
		'single	user mode' and starts up the system again.

     -p	path	Only remove the	specific mount-path.  Send a UMOUNT RPC	to the
		NFS server.  This option implies the -host option.

     -v		Verbose, additional information	is printed for each processed
		mounttab entry.

FILES
     /var/db/mounttab  mounted nfs-file	systems
