Lustre discuss - Aug 2008 - lustre patches for e2fsprogs version 1.41.0?

Hello,

Are there any plans to support the latest e2fsprogs version with the lustre 
patches? If yes, is there a a bug in the bugzilla where the status can be 
viewed? 

Greetings

Yes, we update e2fsprogs to follow upstream fairly regularly, and will
be making a release based on 1.41 fairly soon.  Is there something
specific you are looking for from the 1.41 release?

The largest difference is that 1.41 has upstream support for the Lustre
extents format (also used in ext4), but the code is completely different.
It would be interesting to see whether the upstream e2fsck can fix all
of the test cases we have for corrupted extents.

Cheers, Andreas

Where is this module located? I didn''t find any hint in the lustre wiki
about
this module and therefore I don''t have any idea where to check out.

I''ll try this next week.

It _should_ be available in the same place as the lustre CVS, in a module
called "lustre-e2fsprogs" insted of the normal "lustre"
module.  That said,
I''m not 100% sure because I don''t use the external CVS.

Alternately, you can get the e2fsprogs-1.40.11.src.rpm.  This includes
_most_ of the patches in .../patches (except a few newer ones only in CVS)
and are already applied to the sources.  This directory can be moved over
to the e2fsprogs-1.41.x tree and applied with "quilt push -a" (which
will
fail at the first one, which adds -sun1 to the e2fsprogs version ;-).
