 I'm trying to set up Luster on Debian (server  clients). Any hints out

Hi Mario,

It can be done, but be prepared to jump through a few hoops for the
server side.

Client side is pretty straight forward;

make debs

should give you some userspace debs and a module-assistant package for
the client kernel modules.

The simplest thing to do for server kernel  modules  is to grab the
redhat kernel sources and use those to build the server kernel, as
detailed here.

http://wiki.whamcloud.com/display/PUB/Walk-thru-+Build+Lustre+MASTER+on+RHEL+6.1+from+Whamcloud+git

I could not get the rpmbuild -bp step to work correctly using rpm under
debian (although I didn't try very hard), so you might want to do that
on a centos machine.

Once you've patched the kernel you can generate a deb with make-kpkg.
I am not sure whether the debian build targets can cope with the server
modules at the moment; you might have to install those by hand...

Cheers,

Guy

Re: [Lustre-discuss] Latest RHEL/CentOS kernel that compiles against Lustre 1.8 git tree?

2012-04-02 Thread Jeff Johnson
FYI, I tested the Lustre 1.8 patch that provides support for 
2.6.18-308.1.1 and while it does successfully compile the resulting 
changes in the kernel severely impact the isci (Intel SAS) driver. 
Romley (new Xeon-E5) systems booting this driver panic during boot, just 
after switchroot. I will capture the trace and post it, it appears to be 
the result of patch changes to jbd.

 Heh. Nice imagery Jeff. Yes, this patch is still under active
 development and also note that it will not be able to complete autotest
 until we switch it to use RHEL5.8 by default (hopefully soon, but this
 had been on hold until we saw whether we needed RC3 for 2.2). So, if you
 are willing to test the latest patch that would be appreciated and could
 accelerate things (please post your findings on the JIRA ticket), but
 regardless we should have this work completed in the near future.
