fixmount -- fix remote mount entries
fixmount [-adervq] [-h name] host ...
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.
-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.
/etc/mtab
List of current mounts.
/etc/rmtab
Backup file for remote mount entries on NFS server.
mtab(5), rmtab(5), mountd(8), showmount(8)
No attempt is made to verify the information in /etc/mtab itself.
Since swap file mounts are not recorded in /etc/mtab, a heuristic spe-
cific 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 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.
