Hi there!

I've installed Gentoo onto a 4Gig partition, and although ti does everything I want it to do (almost) I want to duplicate the entire thing for testing purposes AND also make more space by duplicating it into a larger partition (7Gig).

However, I tried this by making an image using partimage (excellent program otherwise) and I have the duplicated partition running fine except the extra space is not used (the 7Gig partition now appears as a 4Gig!!!)

Is there something I am doing wrong here? Well, there obviously is but what?

any help would be great!

The only drawback to PartImage that keep me from using it is that it requires the two partitions (source and target) to be the same size. If the target is larger than the source, PartImage will truncate the target partition to the same size as the source partition.

You could try cfdisk to edit the target partition after transfer to try to increase the size of that partition.

Otherwise, you could reformat the target, increase the size, then use tar to make an archive of the source partition, then pipe it through tar to unpack it in the target partition.

Sorry, but I don't remember the correct syntax. I beleive you can find is somewhere in the LQ forums.

Not true - the partition is unaffected.
The filesystem is however copied as-is. Most filsystems have a resize command that by default expands the (target) filesystem to the size of the partition. Works fine on expand - shrinking can be a totally different matter.

I agree tar or cp is a better option ...

For gentoo, for space relief it is usually sufficient to move the directories most heavily used ny portage to other partition(s).
