Default H.D. install problem -

I removed the 80gB WindowsXP hard drive [/dev/sda] and replaced it with
a larger drive on which I installed F9 from a Live CD. The second drive
[dev/sdb] has F8 on it, my primary Linux until this morning. I would
like to extract some configuration date from the F8 drive but have been
unable to access it no matter what I've tried. The problem is that it
uses the LVM designations which I can't seem to deal with instead of the
old "/dev/sda" etc. I am lost!


Fortunately I have another F8 computer with most of the config data
duplicated on it but I still want to be able to use the secocnd drive in
this box. I'm not sure what data to provide or even what question to
ask other than how do I go about getting access to the old F8 system.
Grub only offers the the new F9 install.


Fdisk shows the following:

# fdisk -l /dev/sda

Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders

# fdisk -l /dev/sdb

Disk /dev/sdb: 80.0 GB, 80026361856 bytes

Any suggestions appreciated.

The utilities vgscan, pvscan and lvscan will assist you in your goal.

You now have your partition list, which you can mount.

Ok, I can't mount it on / because that's already used but I can mount it
on /mnt and copy files at least. Thats a start, more than I've been
able to do so far!


mount /dev/mapper/VolGroup00-LogVol00 /mnt

I'll need to figure how to get grub to boot it ...

But that's a big help.

Thanks.

Bob
