This is a good sign. You have both drives added into the lvm and they are showing up
as free space. You now need to run lvextend and then resize the filesystem.
lvextend --help
File descriptor 4 left open
lvextend: Add space to a logical volume
lvextend
[-A|--autobackup y|n]
[--alloc AllocationPolicy]
[-d|--debug]
[-h|--help]
[-i|--stripes Stripes [-I|--stripesize StripeSize]]
{-l|--extents [+]LogicalExtentsNumber |
-L|--size [+]LogicalVolumeSize[kKmMgGtT]}
[-m|--mirrors Mirrors]
[-n|--nofsck]
[-r|--resizefs]
[-t|--test]
[--type VolumeType]
[-v|--verbose]
[--version]
LogicalVolume[Path] [ PhysicalVolumePath... ]
The command should be something like the following:
lvextend -L +596.12G MythData
Where MythData is whatever you called your logical volume when you installed it.
Then after this step a pvs should show very little space free on the disks.
After this you will have to resize your filesystem on the lvm. I don't believe you
stated what filesystem you are using but I will give you an example. For reiserfs
(this is what I use) the command is simply
resize_reiserfs /dev/VolGroup00/MythData
Assuming MythData is the name of your logical volume again...
