it was the automounter.
Regards Stots
=================================
The original query was :
I have some very strange problem in solaros 2.5.1,
some of my nfs mounted disks become unmounted without
any reason ......
(no one is umount the disks !!!!!!!)
Any idea ?

Either you have a timeout value on mount or your using automounter would
be my guess. Turn debugging on the daemons and that will give more info.
From: Fong Vang
Someone is probably sitting on the mount. They don't have to actually use
it - as long as they're in the directory, it becomes unmountable. Use
utilities like fuser to determine which user is in the directory
(filesystem). There are other ways as well (the proc utilities, e.g.).

Are you using automounter perchance?

Hi,
Are these filesystems mounted via automountd ? Is this machine a NIS(+)
client ?
If yes, there is a specification for automounted nfs filesystems. The fs is
umounted after an idle time and auto-remounted if it's needed.
E.g. server:/export/foo is automounted on /export/foo.
$ mount | grep foo
$ cd /export/foo
$ mount | grep foo
/export/foo on server:/export/foo (options) on (date)
And it will be umounted if it's not used for X minutes ...
Ciao,

is it mounted thro automount?
From: Roger Fujii <rmf@lookhere.com>
check your automounter. If this is used to mount it, it will
automagically unmount it....

Hi,
just to tell you that the automounter dismount the partitions
if nobody use it.....but if you try to go in that directory where you have
mounted it,
tl will be mounted again.
