Hi,
This is perfectly possible with LVM. First add the HD (aka the HW RAID
volume) to the OS. Then do a pvcreate on that disk so that LVM can use
it. Then do a vgextend, this adds the disk to the volume group. A
vgdisplay should then show that you have again free space in the
volume group. Then you can do a lvextend and resize2fs as normal.
Regards,
Tim

Hoping the problem magically goes away by ignoring it is the
