as far as I can see client rebuilding is not working via rpmbuild.
there appears to be no SRPMS directory in the 1.8.7-wc1 client tree and
rpmbuild --rebuild lustre-client-source-1.8.7-wc1_2.6.18_274.3.1.el5.x86_64.rpm
error: source package expected, binary found
error: lustre-client-source-1.8.7-wc1_2.6.18_274.3.1.el5.x86_64.rpm cannot be installed
suggests this is not the correct rpm - (looks like a source tree install binary ..??)
we are stuck - need to compile the1.8.7-wc1 client against our own kernel ... any ideas welcome.
i think i once did this by compiling the lustre source on a tree without the presence of a patched kernel, which defaults to client only build.
would this work??
