[Linux-cluster] patch 2.6 kernel without modules

[Jonathan Salomon]

Hi all,

I want to use GFS for a webcluster with shared data through a iSCSI SAN. 
The cluster nodes are diskless and boot through PXE by downloading a 
kernel and rootfs that is stored in RAM. I have built a custom minimal 
Linux system with LFS (http://linuxfromscratch.org) to keep the image as 
small as possible (the smallest Fedora/RedHat I could get by stripping 
RPMs was still 650MB).

I would like to work without kernel modules and therefore I would like 
to know whether it is possible to patch the 2.6 kernel to include GFS 
'statically' (i.e. no kernel modules). As far as I cann tell the 
cluster-1.02.00 package I downloaded builds kernel modules.

In addition I would like to know what minimal requirements I need to use 
GFS. The load balancing itself will be done on other machines with a 
different setup. Hence I would like to refrain from installing any of 
that functionality on the cluster nodes. From reading the docs I get the 
impression GFS needs a whole lot of clustering packages.

Thanks!
Jonathan
