Also i could get some rpms for patched kernel from lustre download site for lustre-ldiskfs-3.2.0-2.6.18_164.11.1.el5_lustre.2.0.0.1.x86_64.rpm lustre-modules-2.0.0.1-2.6.18_164.11.1.el5_lustre.2.0.0.1.x86_64.rpm, kernel-2.6.18-164.11.1.el5_lustre.2.0.0.1.x86_64.rpm.But i am not sure if i can use the same patched kernel i was using for Single MDS setup.
