RPC.UMNTALL(8) BSD System Manager's Manual RPC.UMNTALL(8)
rpc.umntall -- notify NFS servers about unmounted NFS file systems
rpc.umntall [-e expire] [-h host] [-k] [-p remotepath] [-v]
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
remote NFS server. It is called automatically without any parameters
during 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
-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
isn't 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
/var/db/mounttab mounted nfs-file systems
The rpc.umntall utility first appeared in FreeBSD 4.0.
