Thanks for the additional info. It looks to me like that process should be modified for shrinking to: 1. Resize filesystems 2. copy to outdisk (w/o size change) 3. Edit partition to match resized filesystems 4. Truncate outdisk This should work for msdos labeled disks. For GPT, I am not sure what parted would do when you truncate it (which will chop off the duplicate GPT table). -- Brian C. Lane / Anaconda Team Port Orchard, WA (PST8PDT)
