Make sure they are clean before the process starts. Take backups. First make sure you have enough free space in your LVs. Then use a combination of pvmove and pvresize to shrink your PE that corresponds to that partition. Then shrink the partition in the partition table. Check your file systems. You may be able to revert any damage done at this point. (Optional) Grow the PE to match the new partition size (e.g. if there's lack at the end you left.) Grow LVs based on newly available space. Check your file systems. This should be very quick. Growing is a lot less tricky that shrinking, but it still has to be done in the right order. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
