Thanks for replying so quickly, Jake.
After posting, I kept looking. I found a document on the web called
"Accessing a Fedora Logical Volume from Ubuntu".
You were right about the need to install software. I did.
The document next told me to load the dm-mod module. I did.
It next told me to run vgscan. I did.
I was told that all physical volumes for the volume group VolGroup00
couldn't be found. That confirms your point about needing both disks
connected.
I think I might get a second gadget and see what happens when both
physical volumes comprising the logical volume group are connected.
I think that's my best shot, because I haven't got a clue about how I
might get the CPU fan on computer A going again. If I knew that, I would
also have known enough not to accept the default installation in Fedora
9, in so far as it used LVM!!
Thanks again,
Leslie

Logical Volume Management.
Computer A will no longer boot up. I suspect it has something to do
with the fact that the fan over the CPU doesn't run.
I got computer B, another old computer, going, running Ubuntu 8.10.
It has a single hard drive and no facility to add a second.
I hoped to be able to get data off the two old hard drives, in
particular, photographs. I got a gadget that allowed me to plug an
IDE drive into a USB port. I removed one of the old drives from
computer A and attached it to computer B via the gadget.
When I run fdisk -l on computer B, I'm told that the attached drive
is sdb1.
However, I can't mount sdb1. When I try, I get the message "unknown
filesystem type 'LVM2_member'".
Does that mean that there's no way for me to get the data from
computer A's drives to computer B?
Thanks for reading this.

You need to install the stuff to handle LVM in ubuntu, as i recall it
doesn't come with it by default.
if you spanned the LVM over both disks you will probably need to have
both of them connected to use the volume effectively.
If you can get the fan spinning again it'd probably be enough to get
the other one to boot.
