------- Comment #1 from sandeen@...hat.com  2009-03-05 09:26 -------
Is this something you can reproduce?  I'm not remembering anything related
offhand other than an early bug in the extent code, which I think should be
fixed well before 2.6.27.

If you find inode #2621457, I expect that it is very fragmented, and I'd guess
that any access to it (reading it, that is, or perhaps extending it) will trip
this error.

If you can try a later kernel, maybe 2.6.27.x or 28.x or even .29 it'd let us
know if the problem still exists; if not maybe there is more debugging we can
do.

Providing an e2image -r of the filesystem would also let us see what kind of
layout that file has, though from your comments I'm guessing this may not be
possible due to security reasons.
