The am-utils manpages were un-mandocafied, un4.4BSD'ed with CSRG copyrights regressed to 1989. This work was done by Brian Handy who I am very greatful to. (only a few minor tweaks by me) Submitted by: Brian Handy <handy@lambic.physics.montana.edu>

.Sh NAME
|
|
.Nm fixmount
|
|
.Nd fix remote mount entries
|
|
.Sh SYNOPSIS
|
|
.Nm

|
|
.Op Fl h Ar name
|
|

|
|
\&...
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is a variant of
|
|
.Xr showmount 8
|
|
that can delete bogus mount entries in remote
|
|
.Xr mountd 8
|
|
daemons. The actions specified by the options are performed for each
|
|
.Ar host
|
|
in turn.
|
|
.Sh OPTIONS
|
|
.Bl -tag -width Ds
|
|
.It Fl a Fl d Fl e
|
|
These options work as in
|
|
.Xr showmount 8
|
|
except that only entries pertaining to the local host are printed.
|
|
.It Fl r
|
|
Removes those remote mount entries on
|
|
.Ar 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
|
|
.Pa /etc/mtab .
|
|
.It Fl v
|
|
Verify remote mounts. Similar to
|
|
.Fl r
|
|
except that only a notification message is printed for each bogus entry
|
|
found. The remote mount table is not changed.
|
|
.It Fl A
|
|
Issues a command to the remote mountd declaring that
|
|
.Em 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.
|
|
.It Fl v
|
|
Be quiet. Suppresses error messages due to timeouts and
|
|
.Dq Program not Registered ,
|
|
i.e., due to remote hosts not supporting RPC or not running
|
|
.Nm mountd .
|
|
.It Fl h Ar name
|
|
Pretend the local hostname is
|
|
.Ar 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
|
|
.Fl v
|
|
only.
|
|
.Pp
|
|
This option also saves time as comparisons of remotely recorded and local
|
|
hostnames by address are avoided.
|
|
.Sh FILES
|
|
.Bl -tag -width /axx
|
|
.It Pa /etc/mtab
|
|
List of current mounts.
|
|
.It Pa /etc/rmtab
|
|
Backup file for remote mount entries on
|
|
.Tn NFS
|
|
server.

|
|
.Sh BUGS
|
|
No attempt is made to verify the information in
|
|
.Pa /etc/mtab
|
|
itself.
|
|
.Pp
|
|
Since swap file mounts are not recorded in
|
|
.Pa /etc/mtab ,
|
|
a heuristic specific to SunOS is used to determine whether such a mount
|
|
is actual (replacing the string
|
|
.Ql swap
|
|
with
|
|
.Ql root
|
|
and verifying the resulting path).
|
|
.Pp
|
|
Symbolic links on the server will cause the path in the remote entry to differ
|
|
from the one in
|
|
.Pa /etc/mtab .
|
|
To catch those cases, a filesystem is also deemed mounted if its
|
|
.Em local
|
|
mount point is identical to the remote entry.
|
|
I.e., on a SunOS diskless client,
|
|
.Ic server:/export/share/sunos.4.1.1
|
|
is actually
|
|
.Pa /usr/share .
|
|
Since the local mount point is
|
|
.Pa /usr/share
|
|
as well this will be handled correctly.
|
|
.Pp
|
|
There is no way to clear a stale entry in a remote
|
|
.Nm mountd
|
|
after the local hostname (or whatever reverse name resolution
|
|
returns for it) has been changed. To take care of these cases,
|
|
the remote
|
|
.Pa /etc/rmtab
|
|
file has to be edited and
|
|
.Mn mountd
|
|
restarted.
|
|
.Pp
|
|
The RPC timeouts for
|
|
.Nm mountd
|
|
calls can only be changed by recompiling. The defaults are 2 seconds
|
|
for client handle creation and 5 seconds for RPC calls.
