/stand not mounted

[Animesh Chakraborty]

Hi All,
My server is up and running but when I do bdf
I can not see /stand.
vmunix was there at /stand only.
Any hints ?
Can I mount it manually now ?

Thanks
Animesh

Are you 100% sure that /stand is not there? It could be that someone has created an alias for bdf that only shows the vxfs filesystems. Issue "bdf -t hfs" and /stand should show up in this list. Also, verify with "mount" or "mount -p" that /stand is mounted.

Regards,

Vincent

Hi Vincent,
The bdf -t hfs doesn't show /stand.
Thanks for your response.

Hi

It is so funny. I faced same problem once, I am not sure that ur problem is same or not. My problem was mount command was 0 bytes. So it was not mounting.
For Booting HP system /stand should not be mounted. It will access vmunix by using cntndns1lvm device file.

Please go to /sbin directory and confirm this.

Best of luck

Hi,
somebody might be unmounted the /stand, if mount not showing the /stand then you can mount it, make sure the vg and lvol while mounting, usually vg00 and lvol1

Hi,

As suggested by Vincent check to see if it
is really mounted, try using mount -p
this will check the /etc/fstab file.
Also view /etc/fstab file to see that nobody
has changed it.

What other files are reported under /stand ?

You can't unmount /stand whether you are in
multi-user mode or single user.

Make sure your /etc/fstab file shows /stand

/dev/vg00/lvol3 / vxfs delaylog 0 1
/dev/vg00/lvol1 /stand hfs defaults 0 1
/dev/vg00/lvol4 /home vxfs delaylog 0 2
/dev/vg00/lvol5 /opt vxfs delaylog 0 2
/dev/vg00/lvol6 /tmp vxfs delaylog 0 2
/dev/vg00/lvol7 /usr vxfs delaylog 0 2
/dev/vg00/lvol8 /var vxfs delaylog 0 2

When was the system last booted?
How size is the /stand/vmunix file?

hi,

Independant of your run-levels you can umount /stand at anytime it makes no error .

You can try the following,

mount -a
verify /etc/fstab
do an fsck /stand
verify /stand directory exists or not

Yes of course you can umount /stand
but who does unmount it??

I've not seen this before, but it beckons
the question why the /stand/vmunix exists
but the file system is not mounted.

Hi Kaps,

Kaps off( In lieu of hats off)

Varghese here. What u said is 100% correct -- we can mount or umount the /stand at any time. But what we need to know is how can it happen like, /stand did'nt get mounted at the time of booting? and errors were getting flashed in the syslog file saying "can't get namelist" blah blah blah !!!.

Hoping to get more ideas from u all ..
Cheers,
Mathew

Hi ,
I am 100 % sure that /stand in not mounted.
and when I do cd /stand then #bdf .
I am still in / (root) file system.
my /etc/fstab entry is correct:
/dev/vg00/lvol3 / vxfs delaylog 0 1
/dev/vg00/lvol1 /stand hfs defaults 0 1
/dev/vg00/lvol4 /tmp vxfs delaylog 0 2
/dev/vg00/lvol5 /home vxfs delaylog 0 2
/dev/vg00/lvol6 /opt vxfs delaylog 0 2
/dev/vg00/lvol7 /usr vxfs delaylog 0 2
/dev/vg00/lvol8 /var vxfs delaylog 0 2
/dev/vg00/leds /eds vxfs delaylog 0 2

And I am getting all the symptoms for missing vmunix like no namelist etc. etc.
In syslog I am getting :
Jun 10 19:43:14 CTXPRD vmunix: NOTICE: Cannot open module krm on path /stand/dlk
m/mod.d
How does it really matter that /stand file system is mounted or not ?

Thanks all
Animesh

Hi all,

Varghese nice to here you. See i am not a king here , but my idea is as follows,

While booting the machine it does not use the normal devicefile ie /dev/vg00/lvol1 to read the kernel. It may be using some other device driver like /dev/dsk/cXtXdXs2LVM etc.

Did you try an fsck on lvol1 ?. Try that.

Best of luck ,

Have you checked to see if /etc/mnttab is corrupt, out-of-date, whatever. If it thinks /stand is already mounted for some reason, it could be due to this.

Robin

[Animesh Chakraborty]

Hi Robin,
Currently there is no entry in /etc/mnttab for /stand
and the /etc/mnttab file looks ok.
Anyway thanks for your thought.

Animesh

[KapilRaj]

hi,

Robin's point is good. try the following ,

rm /etc/mnttab
mount -a
bdf

Look for the result ,,

Good luck

make sure it is in your /etc/fstab

It is okay since the system is up, it's just not mounting.

make sure with lvdisplay -v /dev/vg00/lvol1
then try
mount /dev/vg00/lvol1 /stand

mount -p > /etc/fstab
if you are happy with what it currently mounted automatically mounting at boot.

Later,
Bill
