It looks like the machine can see the second drive and the lvm that's on it /dev/sdb2, but it has the same VolGroup name as /dev/sda2.
Yes, this is common and annoying. Here is the guide that I followed when it happened to me:

I filed bug 461682 (https://bugzilla.redhat.com/show_bug.cgi?id=461682), requesting that the default volume names not be so generic - they now incorporate the hostname, so this problem should be much less common in F11+.
