Re: [linux-lvm] Automatically GROW an LV to max size

here's a simple script with a CL check to cut what you want.

Heinz    -- The LVM Guy --

cmd=`basename $0`
if [ $# -ne 1 ]; then
   echo -e "$cmd -- please call with just one logical volume path\n"
   exit 1
VGNAME=`echo $LVNAME|sed 's!/dev/!!;s!/.*$!!'`

FREE_PE=`vgdisplay $VGNAME|sed '/Free.*PE/!d;s!^.*Size !!;s!^ *!!;s! .*$!!'`
lvextend -l+$FREE_PE $LVNAME
