Is there instructions on how to use the patchless client on RHEL4 ? For version 1.6.2 We would prefer a rpm, but we are not scared of doing a build if needed. Brock Palen Center for Advanced Computing brockp at umich.edu (734)936-1985

I used something like: ./configure --without-qsnet --disable-liblustre --disable-ldiskfs --disable-server --enable-tests --with-linux=/lib/modules/`uname -r`/build && make rpms to build it.
That worked thank you very much! Website still isn''t back up?

Is there a bug number or details you can point me to?

(see http://wiki.lustre.org/index.php?title=Patchless_Client https://bugzilla.clusterfs.com/show_bug.cgi?id=12652 https://bugzilla.clusterfs.com/attachment.cgi?id=7237) There are also some performance issues because the RHEL4 kernels lack some features available in newer kernels.
