I searched the web and found a couple of how to's the links are:
(this one shows the LVM tools GUI)
(this one explains the concepts and useage of the LVM... also explains what files are needed and how to run commands)
It appears as though I can fix this by running the following commands: (from http://www.tldp.org/HOWTO/LVM-HOWTO/removeadisk.html
# pvcreate /dev/sdf // to prep the disk
# vgextend dev /dev/sdf // to exend the partition
#pvmove /dev/hdb /dev/sdf // to move data from one disk to another
# vgreduce dev /dev/hdb // to remove from system; as per my understanding of the directions, this should make the disk ready for removal or reallocation of disk space.
Then it appears I need to create a new volume by:
# pvcreate /dev/hdb
which should create a volume group descriptor at the start of disk.
# dd if=/dev/zero of=/dev/diskname bs=1k count=1
# blockdev --rereadpt /dev/diskname
the page http://www.tldp.org/HOWTO/LVM-HOWTO/initdisks.html
The following commands will destroy the partition table on the disk being operated on. Be very sure it is the correct disk.
Then I'll need to create a new partition by running
# pvcreate /dev/hdb1
# vgcreate my_volume_group /dev/hda1 /dev/hdb1
to make a new group.
The web page http://www.tldp.org/HOWTO/LVM-HOWTO/createvgs.html
states there is a different command for LVM v1
to check which version I had, and recived
LVM version: 2.02.06 (2006-05-12)
Library version: 1.02.07 (2006-05-11)
Driver version: 4.7.0
so the command should work.
# vgchange -a y my_volume_group
should activate the volume.
Then it looks like I can run
# lvcreate -L 1500 -ntestlv testvg /dev/sdg
to create a partition volume in a logical volume to be allocated from a specific physical volume in the volume group (/dev/sdg)
That should repair my wrongly sized volume?
I recived this list of commands
Available lvm commands:
Use 'lvm help <command>' for more information

lvmchange With the device mapper, this is obsolete and does nothing.

I don't think I'm going to try the command line to repair this, but I thought it was some useful information.
I think re -installing is going to be my best option to fix this
Please let me know if there is an "easier" way to repair my volume size.
Also some feed back about using 'file-roller' to make a back up of my current home directory (for my current bookmarls and e-mails) is a good way to make a back up.
