Well, it looks like /dev/sdb2 is part of an LVM setup.  Possibly this
drive was setup previously using LVM, or maybe this drive is a member
of your main LVM setup and the drive you actually want is something
different.  Unfortunately, I haven't used LVM very much, so I am not
very familiar with it.  Here are a couple of How-Tos and guides to
hopefully help out:

http://www.tldp.org/HOWTO/LVM-HOWTO/index.html
http://www-128.ibm.com/developerworks/library/l-lvm/
http://www-128.ibm.com/developerworks/library/l-lvm2.html

You may also try posting the output from dmesg (without the | less) or
the output from the lshw -class disks command.  It might help me or
someone else figure out exactly what is setup.

Sorry I can't be of more help.
