Currently, trying to run OrangeFS over IB using QLogic's OFED results in an error similar to: "Error: init_connection_modify_qp: ibv_modify_qp RTR -> RTS: Invalid argument."
This issue was discussed back in March 2010 in this thread: http://www.beowulf-underground.org/pipermail/pvfs2-users/2010-March/003077.html Attached is a patch to resolve the issue, it's just a change to the values of the timeout, retry_cnt, and rnr_retry in the attr struct passed to ibv_modify_qp(). We'll get a more permanent solution in CVS. For now this provides a work around for those wanting to run OrangeFS over QLogic IB. Michael
