[James Hawtin]

pvmove has fixed the 2GB file offset problem. YAY! it works great however
I did get it to segv ;-)

Summary, I have a 22 gig lv, on one disk which I want to move on off it,
There is enough disk space on two other pvs.

So pvmove -v -n oolon3_lv /dev/ide/host2/bus0/target0/lun0/part4

Should work.... in theory

However it didn't a segv was produced, I solved the problem by specifying
the LE extent ranges and PEs to move them two, a two stage op, but still,
it should not have segved.

More detailed info from this point...

Here is the setup

pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/ide/host2/bus1/target0/lun0/part2" of VG
"sunset_vg" [30.84 GB / 19.66 GB free]
pvscan -- ACTIVE   PV "/dev/ide/host2/bus1/target1/lun0/part1" of VG
"sunset_vg" [19.03 GB / 8.09 GB free]
pvscan -- ACTIVE   PV "/dev/ide/host2/bus0/target0/lun0/part4" of VG
"sunset_vg" [35.06 GB / 13.06 GB free]
pvscan -- total: 3 [85.07 GB] / in use: 3 [85.07 GB] / in no VG: 0 [0]
