Does pvmove --alloc anywhere help? Alternatively, you can specify exactly which extents go where, like in "pvmove --test -n lvname.to.move /dev/pvold:20-27 /dev/pvnew:732-739". obviously, remove --test, if it seems to do what you meant. To see which what is where, and which extent ranges are free, I tend to use variants of pvs -o vg_name,lv_name,pv_name,pvseg_start,pvseg_size,seg_pe_ranges -Opv_name,pvseg_start Note that pe_ranges are inclusive, (end of the range is: pvseg_start + pvseg_size -1). hth, -- : Lars Ellenberg : LINBIT | Your Way to High Availability : DRBD/HA support and consulting http://www.linbit.com DRBD® and LINBIT® are registered trademarks of LINBIT, Austria. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
