[mythtv-users] Moving a LVM harddrive (F10)

I have currently a back and frontend running which I thought would be the
main main myth box for a while. However I realised I bought a microATX case
which meant I needed to reconfigure when I upgraded.

So it has meant I am going to build a new myth box. The thing is that I
built the old one with a 8GB HD for the OS and a 250GB HD for the myth
related files (eg video,music etc). Furthermore the 250GB was setup as a LVM
in anticipation of adding more to this existing box. However it is woefully
inadeqaute and the 250GB will have to move to the new box. So as it stands
things look like this:

Partition table entries are not in disk order

[root at localhost ~]#

I am thinking I should be able to install the /dev/sdb HDD into the new
computer, load LVM tools and have it pick up without issue? What are the
pitfalls I should look out for? BTW I think it is formatted as ReiserFS.
