Lustre discuss - Apr 2007 - Lustre on Debian ETCH with RHEL4 Kernel

Hi all,

We recently got some HP-DL365 machines with the p400i controller. This
presented a problem for us on Debian ETCH when we rolled the kernel back to
2.6.12.6 as the cciss driver wasn''t new enough, and the available ones
from
sf.net didn''t work out either.

Patching the 2.6.18 kernel, though I am sure will work, is probably not
ideal for production environments.

To not tell a very long tale (2 days long really) of trying various options,
we decided to try and run the supplied lustre kernel for RHEL4 on Debian.
Barring a few very minor notes, the kernel, lustre-modules as well as lustre
package were converted to debs and installed.

I am yet to run any proper tests, however, everything is up and running via
the provided test scripts.

If anyone is interested in further details or wants to throw a red flag up
regarding such a deployment, please do let me know.

Thanks,

I have patches for 2.6.18 and 2.6.20 for lustre 1.4.7 and 1.4.9 that
we use productively at work and there is a debian package for the
upcoming lustre 1.6 in Debian that makes building your own lustre
kernel easy as pie.

If anyone is interested then shout.

Shouting ... :) If you could kindly e-mail me the 2.6.18 patch for 1.4.9, it
would be much appreciated.

Mustafa.

I had the same problem (on dl320s with p400). I fixed it by patching
the 2.6.12.6 driver. patch attached.

I also had problems with the tg3 driver. I ended up downloading a
tarball from broadcom and replaced the 2.6.12.6 ones.

So far, it works fine running 1.6beta7.
