Duplicated mount points

[LAFDAL_1]

Hi,
My bdf gives all the automounted file systems in double. I configured the system to have autofs.
My system is N4000 HP9000
The OS is HPUX 11.0
Waiting to hearing from you ASAP
Thanks

Is the same remote filesystem mounted on the same mountpoint twice ? Or the same filesystem mounted on different mountpoints.

What is the content of your /etc/auto_master file ?

automount with stalemounts causing duplicate mnttab entries & lock problems.
symptoms of automount are: stale nfs handles are
seen in mnttab after an unmount and when the
mount is repeated (in this case a cdrom...) the
mnttab contains two entries for the device. One
of which is invalid. This second (stale) handle
causes subsequent locking problems.
automountd

... is this patch installed ?

The contents of auto_master file are :
/net -hosts -soft
/- /etc/auto.usr
+auto_master


The contents of the auto.usr file are :

/sapmnt/FEP -rw,hard relFEP_100BT:/export/sapmnt/FEP
/EDI -rw,soft,retry=0 relFEP_100BT:/export/EDI
/users1 -rw,soft,retry=0 relFEP_100BT:/export/users1
/users2 -rw,soft,retry=0 relFEP_100BT:/export/users2
/users3 -rw,soft,retry=0 relFEP_100BT:/export/users3
/users4 -rw,hard relFEP_100BT:/export/users4
/nfs_shared -rw,soft,retry=0 relopt_100BT:/export/nfs_shared
/usr/sap/trans -rw,soft,retry=0 K05H:/usr/sap/trans

Hi alex,
The patch is not installed yet. But we are planning to do it.
But, since system is in production, and this this patch requires system reboot, we didn't do it right now.
But, T want to be confirmed that this patch solve surely the problem.

Regards.

I spoke to our netwks team as I was typing (they passed by my desk) .... they seem to think it most probably would and it's the best place to start ......ie

if there's known issues with bdf & automounter lets rule them out first !

ps be warned the patch has dependancies !

What is the meaning of the entry "+auto_master" in your auto_master file ?
As I understand, this includes your auto_master file in itself. So all your entries in that file are double, maybe that causes double mounts. I agree with the patch installation, but since all filesystems are involved, look at the modification time of the /etc/auto_master file. Has it been recently changed ? Has there been a recent NFS patch installation ?

Hello,
Just check whether you have started your automounter process when one of that was already running.
Just try stopping your automounter process and then start them again.
I have faced the problems when you start automounter twice.
