Missing lvol3 from vg00.

[Trevor Roddam_1]

I have a system where, not by me, the fstab file was edited and the leading "/" from "/dev/vg00/lvol3" was removed. It then looked like "dev/vg00/lvol3".

Then the system was rebooted.
Successfully I might add.

lvol3 now appears as "/dev/root" from a bdf.

Question: How do I get this back to normal.
The disk has been mirrored after the misfortunate incident. the command was "lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c0t2d0"

Some details.
HP-UX 11.0

"lvlnboot -v" returns Boot on lvol3.
System performs as normal.

Any Ideas?

/dev/root This happens when sometime the system was booted into lvm maintenance mode.

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

Hi,

since disk is mirrored, even the mirrored disk also contains same fstab as in first disk. since your system is normal, edit the fstab, add the / to the missing path(dev/vg00/lvol3).

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

in the next reboot all mounts will be normal.

Thanks for your help.

I'll be trying this later on and send forth the happy news.

Thanks.
Trevor.
