NAME
rpc.umntall —
notify NFS servers about unmounted NFS
file systems
SYNOPSIS
rpc.umntall |
[-e expire]
[-h host]
[-k] [-p
remotepath] [-v] |
DESCRIPTION
Therpc.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:
-eexpire- 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).
-hhost- 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.
-ppath- Only remove the specific mount-path. Send a UMOUNT RPC to the NFS server.
This option implies the
-hostoption. -v- Verbose, additional information is printed for each processed mounttab entry.
