fixmount(8)

NAME

     fixmount -- fix remote mount entries

SYNOPSIS

     fixmount [-adervq] [-h name] host ...

DESCRIPTION

     fixmount is a variant of showmount(8) that can delete bogus mount entries
     in remote mountd(8) daemons.  The actions specified by the options are
     performed for each host in turn.

OPTIONS

     -a -d -e
	     These options work as in showmount(8) except that only entries
	     pertaining to the local host are printed.

     -r      Removes those remote mount entries on host that do not correspond
	     to current mounts, i.e., which are left-over from a crash or are
	     the result of improper mount protocol.  The actuality of mounts
	     is verified using the entries in /etc/mtab.

     -v      Verify remote mounts.  Similar to -r except that only a notifica-
	     tion message is printed for each bogus entry found.  The remote
	     mount table is not changed.

     -A      Issues a command to the remote mountd declaring that all of its
	     file systems have been unmounted.	This should be used with cau-
	     tion, as it removes all remote mount entries pertaining to the
	     local system, whether or not any file systems are still mounted
	     locally.

     -v      Be quiet.	Suppresses error messages due to timeouts and
	     ``Program not Registered'', i.e., due to remote hosts not sup-
	     porting RPC or not running mountd.

     -h name
	     Pretend the local hostname is name.  This is useful after the
	     local hostname has been changed and rmtab entries using the old
	     name remain on a remote machine.  Unfortunately, most mountd's
	     won't be able to successfully handle removal of such entries, so
	     this option is useful in combination with -v only.

	     This option also saves time as comparisons of remotely recorded
	     and local hostnames by address are avoided.

FILES

     /etc/mtab
	   List of current mounts.

     /etc/rmtab
	   Backup file for remote mount entries on NFS server.

BUGS

     No attempt is made to verify the information in /etc/mtab itself.
     also deemed mounted if its local mount point is identical to the remote
     entry.  I.e., on a SunOS diskless client,
     server:/export/share/sunos.4.1.1 is actually /usr/share.  Since the local
     mount point is /usr/share as well this will be handled correctly.

     There is no way to clear a stale entry in a remote mountd after the local
     hostname (or whatever reverse name resolution returns for it) has been
     changed.  To take care of these cases, the remote /etc/rmtab file has to
     be edited and mountd restarted.

     The RPC timeouts for mountd calls can only be changed by recompiling. The
     defaults are 2 seconds for client handle creation and 5 seconds for RPC
     calls.
