I have been on this list for only a few days now, so I don't know anything about these growfs patches. But I'll guess I can find them somewhere. Unless they're scattered all over the place ;-) I run 6.2-RELEASE by the way. What's the easiest way to get the right growfs version with the necessary patches? growfs scares me more than gpt destroy :) > > hope this helps! Meddling with a FS that has data on it is always scary, no matter what tools you use. But your detailed description helps a lot. So once I updated growfs I'll try this approach myself. Best regards, Richard
