Hello,
I'm new to the LVM thoug silly quesitons. Appreciate any help.

situation is simple.
I have RH3 with LVM on it.
Plus i have external USB ide drive with Fedore 3 ( or whatever the lastest one is ).
The story goes like this :
1. we used to have fedore running on PC.
2. We got server with preinstalled RH3.
3. the PC has been taken away and hard drive left for our purpises.

Task is :
to mount said hard drive.

i can see it under devices ( /dev/sde):

so to my inexperienced eye - the device is there, but i lvm doesn't think(see it ) it is there.
Please advise.
thank you.

I think you may need to "activate" the volume... there is a really handy how-to: http://www.ibiblio.org/pub/Linux/doc...movevgtonewsys

Maybe that will help? I'm not totally sure, I havn't had to do this.. my current project is juggling data between drives in an lvm setup...

Good idea.
But how do i refer to that volume ? Is there a name i'm missing ?
thnx
