Actually, what I'd like is a compressed e2image dump of the file
system, and reproduction instructions so I can try to replicate the
problem in an environment where I can observe it.
See "man e2image" and look for the section for RAW IMAGE FILES for
more details. This will allow you to send me just the metadata of the
file (so I won't see any of the data blocks), but that should be
enough to replicate the problem. It would leak out the directory
names to me, which might or might not be an issue that you would be
concerned about.
There is a "scramble" option which will scramble the filenames, but
that will screw up the htree directory structures, so I'd prefer not
having the filename unless you feel strongly about the filenames being
privacy sensitive --- in which case an e2image with scrambled
filenames is better than nothing.
Cheers,
