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(8C) 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 notification 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 filesystems have been unmounted.	This should be used with  caution,
	      as it removes all remote mount entries pertaining to the local system, whether or not any filesystems are still mounted locally.

       -q     Be  quiet.   Suppresses error messages due to timeouts and "Program not registered", i.e., due to remote hosts not supporting 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.

SEE ALSO

       showmount(8), mtab(5), rmtab(5), mountd(8C).

BUGS

       No attempt is made to verify the information in /etc/mtab itself.

       Since swap file mounts are not recorded in /etc/mtab, a heuristic specific to SunOS is used to determine whether such  a  mount	is  actual
       (replacing the string "swap" with "root" and verifying the resulting path).

       Symbolic links on the server will cause the path in the remote entry to differ from the one in /etc/mtab.  To catch those cases, a filesys-
       tem is 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.
