NAME
fixmount
- fix remote mount entries
SYNOPSIS
[-adervq
]
[-h name
]
host ...
DESCRIPTION
The
utility
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 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 file systems 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
file systems 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(8).
-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 will not 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.
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 file system 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(8)
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(8)
restarted.
The RPC timeouts for
mountd(8)
calls can only be changed by recompiling.
The defaults are 2 seconds for client handle creation and 5 seconds for
RPC calls.
