Hi Libor,

I built Debian packages with the RH kernel for squeeze
and wheezy (http://web-docs.gsi.de/~tstibor/lustre-builds/). 
It is crucial to have the correct version of ldiskfsprogs, otherwise
one is running into problems such as documented at
http://lists.alioth.debian.org/pipermail/pkg-lustre-maintainers/2012-October/000401.html

I downloaded the RPMS version from whamcloud and extracted
the source. At
http://web-docs.gsi.de/~tstibor/lustre-builds/ldiskfsprogs/ 
a patched version to work with wheezy (db-5.X support) can be found. 
This version is also working on squeeze. I guess you can also use the
Lustre 2.2 modules provided at
http://pkg-lustre.alioth.debian.org/backports/lustre-2.2.0-squeeze/ 
The problem documented 
http://lists.alioth.debian.org/pipermail/pkg-lustre-maintainers/2012-October/000401.html
results from an incorrect ldiskfsprogs version which does not know how
to handle "dirdata".

Cheers
 Thomas
