/ mounted to /dev/root ?

[Rusty Sapper]

A group I work with built an N class and set up disk mirroring , but then noticed when they did a bdf that / was mounted to /dev/root. But nothing like that is listed in the fstab. infact in the fstab, / should be mounted to /dev/vg00/lvol8, but it looks like the /dev/root thing is happening first on boot up. Any Idea why and when this is happening?

TIA

This is a common one - usually a result of having been in LVM mainetnance mode recently...

Just type the following to fix:

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

hy rusty

lvol8 mounted like /

mmmmmm
have you started the server with hpux -lm (maintenance mode)?

why / is not munted with lvol3?

You need to recreate the /etc/mnttab.
mv /etc/mnttab /etc/mnttab.bk.

Duncan's recipe should fix this, but just in case if it still shows up as /dev/root you may have to check lvol8 (probably got stale extent).

# lvdisplay -v /dev/vg00/lvol8
==> if you find stale extents continue below ..

# vgchange -a y /dev/vg00
# mv /etc/mnttab /etc/mnttab.old
# mount -a
