/dev/vg00/lvol3 vs /dev/root

[Chris Fung]

Hi all,

I just encounter a strange problem that when I use bdf to check the filesystem structure of my machine.....I found that the root filesystem is mounted to /dev/root. While a different result was shown (/dev/vg00/lvol3) when I use SAM. I've check against the /etc/fstab file and found that the logical volume for root filesystem should be /dev/vg00/lvol3 but not /dev/root.

Now I encounter a problem when I use Ignite backup to take golden image for my system. The backup couldn't be restore because it cannot recognise the different volume name !!

Any idea? Appreciated if you can give me information to solve this problem.

Many thanks,

Chris

This symptom is usually caused by bringing a system up in single user mode and then going to multi user mode.
To fix:
rm /etc/mnttab
mount -a
bdf

Hi Chris:

To repair this do:

# mv /etc/mnttab /etc/mnttab.old
# mount -a

rename your mnttab file and reread your /etc/fstab by doing a mount -a.

Re-run your ignite process after this.

Thanks
