Mount the two fs's, cd into the root of your original fs (for arguments sake /mnt/orig) and then run a find over it. Let's say /mnt/new is the new fs:

find . -type f -xdev -exec cmp {} /mnt/new/{} ;

slip in a -print if you want to be sure it's examining everything along the way.

I think you may need gnu find to do this, as not all vendor finds allow you to substitute in multiple instances of {}.

I'm sure something reasonable can be worked-up in perl in about 10 lines, in an afternoon too.

You could also use two separate finds to assemble two lists of checksums or md5 hashes and then compare them relatively simply with the various text utils unix provides.

As for why they're different, I'm fairly sure a number of reasons have been mentioned over the years and are all in the archive or on NOW. And that's even assuming the files are all there and intact... if they've somehow suffered some problem then there's no need to get exotic. 8)

I ran an NDMP copy on my filer to take some qtrees from one volume to another. When I ran du -s on each directory the results were different in most cases.

The question I have is - Is NDMP copy the tool for the job, and how do I verify the results once I have run it?

Any ideas?
