[Lustre-discuss] Lustre 1.4.6.3 + OFED 1.2.5.5: Error loading ko2iblnd
Hi, My cluster configuration is as follows: Hardware Config: x86_64 Software Config: SLES10.1, 2.6.16.46-0.12-lustre (Stock SP1 Kernel + Lustre patches), OFEDv1.2.5.5, Lustre-1.6.4.3 Status: Lustre + TCP builds and loads fine Lustre + o2ib builds but "ko2iblnd" does not load :-( Applied the Bugzilla patch 12276 to get Lustre compiled with OFEDv1.2.5.5. Configured as follows (see config.out attached): ./configure --with-linux=/usr/src/linux --with-o2ib=/usr/src/ofa_kernel-1.2.5.5 Get the following warnings when building the RPMs: ----------------- WARNING: "rdma_accept" [/usr/src/packages/BUILD/lustre-1.6.4.3/lnet/klnds/o2iblnd/ko2iblnd.ko] undefined!
