ISTR that long ago, "sfdisk -R" would cause a re-read of the partition info and get it imported. You may need to umount the block devices first, and/or turn of LVM (haven't tried it with LVM active). I know it did work, but that was not using LVM and it was on a device that was not mounted anywhere at the time. > <snip> > Thanks > > Dean > <snip sig stuff> -- Bill
