[linux-lvm] Resizing a volume group


I'm running a Fedora Core 1 box using LVM on RAID (lvm-1.0.3-13) I moved
from a pair of RAID1 hard drives to a larger pair of drives by strategically
failing and replacing the drives.

This has left me with the following situation : Volume group lv0 (26GB) resides
on /dev/md1, which are a pair of 250GB partitions. But the lvm tools only see
/dev/md1 as being 26GB (which is what it was on the old hard drives). (Oddly,
vgdisplay does note that the maximum lv size is 250GB).

Is it possible to resize the pv and lv so that they use up the full space of
the partition?
