Re: pvmove unable to move extents to multiple smaller pvs

[Scott Serr <serrs@theserrs.net>]

For anyone out there with this problem...  if pvmove doesn't seem to 
understand specified PE ranges on the source PV, then upgrade to a newer 
LVM2.  Gentoo's current stable .08 does not have this, but the source 
2.00.25 sure does.
