I am focusing my effort on the simplest lustre filesystem consisting of a single OST. I can mount the MDT/MGS and the OST with no apparent errors.
However, when a client is booting and trying to mount, I start getting a log entry on the MGS: Dec 16 08:10:45 nas-0-0 kernel: LustreError: 5732:0:(ldlm_lib.c:1919:target_send_reply_msg()) @@@ processing error (-11) r...@ffff8103dfa61400 x1355301045403661/t0 o38-><?>@<?>:0/0 lens 368/0 e 0 to 0 dl 1292515945 ref 1 fl Interpret:/0/0 rc -11/0 The client loops giving LustreError: 11-0. The mds_connect operation failed with -11.
