Hi,
Excellent question. In our particular situation, we have all of our servers
running OFED 1.2 and the redhat kernel 2.6.9-55. In order to get more
stability, we would like to upgrade to the latest lustre verstion, but that
is not possible without upgrading the kernel, infiniband stack and all IB
dependent libraries. In essense, we have to rebuild our entire cluster to
do that because the latest lustre does not support our kernel, and the
kernel it does support is not supported by our infiniband stack. It's very
annoying, actually. It would be awesome if Sun supported a few kernels
behind the latest and greatest.
