Hi Thomas,

Depending on how recent your version of LVM2 is, you can use pvresize to
do this:

# pvresize /dev/hda2

This will autodetect the new size of the PV and grow it accordingly. One
thing I noticed was that after fdisking the partition, a reboot was
needed to get kernel to see the new size - partprobe does not seem to be
sufficient.

That might have been a quirk though - check the partition sizes in
/proc/partitions to be sure.

Thanks,

Bryn.
