My fault. I was initially inconsistent in deciding what parts of our 
real tree I wanted online. So there is nothing named "A5 11-3". Should 
not be an issue again; sorry to add complication.

Yep, it does.

No problem. Once I've got that done I'll see what I can do with e2image. 
I really appreciate the input so I'd like to do whatever I can if you 
still think it might lead to some sort of bugfix. So far the only 
changes made were to restore the other files that the post-resize fsck 
had to remove/free. Final total was a couple gigs across 7 dirs.

I've looked for any stat differences between the current file tree and 
the one from the backup just before the resize. The only issue found is 
that there appear to be ~200 directories that were not removed by fsck 
but appear to have had their modtimes reset by it instead. The actual 
files contained were untouched. If that is also no big concern then I 
think later tonight, after/if I can get an e2image done, I'll just 
restore their modtimes from the backup to make things pretty again.

Thank you,
Mark
