Works fine here. Maybe your sed doesn't like the delimiter?

Try '/' rather than '!' with sed like "sed 's/\/group//'".

Did you start with a fresh source tree or run "make distclean"
before "./configure --enable-static_link"?

No LV status flags have been changed at all in 1.1-rc.
lv_check_consistency() checks for the 2 possible user land states in lv_status
which are either 0 or LV_ACTIVE.

For fast progress it should be ok to remove the lv_status checks from 
lv_check_consistency().

For further investigation of a possible 1.1-rc flaw ITR, could you send
me (mge@sistina.com) the output files created with

for d in All_volRaid0_PVs
do
	dd if=/dev/YOurPV of=`basename $d`.vgda bs=1k count=4
done

packed into a compressed tar archive?

Thanks,
