I >wonder if this kind of shrinking is possible. I am using ext3. 1. Shrink the filesystem. (For ext3, must be unmounted, so you'll have to this from a rescue OS.) 2. Shrink the logical volume. (I *think* this requires it to be unmounted, so again, a rescue OS is needed.) 3. Shrink the physical volume. (I'm not even sure LVM supports this. If this is your only physical volume, and you are using the extents toward the end, I don't think you'll be able to move the data.) 4. Shrink the partition. (I'm comfortable with fdisk, but gparted is the recommendation I've heard the most.) Long story made short: Don't give LVM space you will ever want back. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
