Just a bit of additional info.  It appears that the first half of the 
mirror has correct mtimes.  The second half of the mirror has wrong mtimes 
on all files, but directory mtimes are fine.  When you go to view the 
mtimes on the GlusterFS, sometimes you will get the mtime from one node, 
sometimes the other, hence the seeming randomness.

Also, I see that zero-length files have correct mtimes on both halves of a 
mirror.

Thanks,
