First of all, heaps of gratitude for the excellent contribution, tremendously helpful tool.

I really like the way you keep my mdadm raids in order, compared to some of the mangling I see under other "rescue disks" (actually rw-writing the preferred minor?)

What brought me to Grml was the fact that you include the dupmerge tool out of the box, but in running it over a large set of video files (around 5 TB at the moment, ext3 filesystem) I'm getting tons of the above error messages on large files (some are up to 16GB). Having such a tool fail on the largest files kind of defeats the purpose doesn't it 8-)

I see you're running v1.70, while Sourceforge lists v1.73 as current (as of 2008!), and I see references on the interwebs to v1.74, so consider this if nothing else a request to update.

If it's not difficult it's also be great to be able to check out another one or two similar deduplication tools unless you've already checked them all out and consider dupmerge2 the best?

Here's a good overview:

My vote would be for freedup and rdfind.

Thanks for your consideration
