Strange filesystem behavior

-> I am experiencing a strange problem on the
-> /home partition of one of our servers
-> (690 MP, SunOS 4.1.3). The problem is that
-> the partition does not appear in "df"
-> or "mount" listings, even though the
-> filesystem appears to be otherwise working
-> fine. This partition is local to the machine
-> (i.e., not NFS mounted). If I type:
->
-> df /home
->
-> I get the error message:
->
-> Could not find mount point for /home.
->
-> If I type:
->
-> df /dev/id002g
->
-> I get normal df output (minus mount point):
->
-> Filesystem kbytes used avail capacity Mounted on
-> /dev/id002g 458511 362250 50409 88%
->
->
-> The filesystem is readable and writeable, it just
-> doesn't show up in df or mount listings.
->
-> Anybody seen this before? Any clues to the problem?

Responses:
Almost everyone told me to look at the /etc/mtab file which
df references (and mount maintains). It was pointed out that /etc/mtab
is not properly updated if the / filesystem is full (not the case
in this instance). It was also suggested that I try to
do a "mount -f /home" to "fake" the mount and add the appropriate
entry in /etc/mtab. Unfortunately the server had to be rebooted
before I got a chance to look at /etc/mtab, or try "mount -f /home".
It was also suggested that the automounter was sitting on /home,
and that is what I suspect was the culprit. However, prior
to rebooting I tried to kill the automounter and that didn't
solve the problem.
