Mounting Logical Volumes

acidblue · 01-05-2006, 10:38 PM

I have an external usb HD case that I put an HD in with a old copy of fc4 on.
But when It's mounted I can only read the /boot partition.
How do I mount the Logical Volumes so I can read the rest of the disk??
Or is it something else?? I'm assuming it's the Logical Volumes.

You need to activate the volume group:

# vgscan
# vgchange -a y
# vgscan
# lvscan

The VG should now be activated and LVs mountable.

I get an error no 'logical volumes found'.
I've mounted the usb HD with>> mount -t ext3 /dev/sda1 /mnt/usb
Like always I can see only '/boot' partition.
Do I have to give vgscan special parameters??

What OS are you using?

Does vgscan detect the volume group after running vgchange?

Also, try running pvscan.

Slackware 10.2
No vgscan and vgchange detect nothing.

What does pvscan find?

pvscan finds nothing.
'no physical volumes found'
vgscan gives me: etc/lvmtab.d has been created, I think thats what
it said, or something simular.
I have no idea what that means.
There must be some way to mount Logical Volumes.
I wonder if it because its on an external usb HD that
it won't mount.
