Thanks for the explanation of why we don't handle the case of two, say, bmi-tcp interfaces well. We actually came up with a reason we wanted to do that a while back, though. On BGL (yeah, all our wierd cases seem to start that way), the servers have two interfaces: one faces the BGL io nodes (172.whatever) and one faces the MCS internal network (140.whatever). We were trying to access the PVFS volume from jazz, chiba, and BGL, but when we did a getconfig, chiba would try to contact the server at 172.whatver and timeout. I think now the toplogy between the three clusters isn't very condusive to such a mounting scheme, but if we wanted to try again one day, is there a good way? Would something like configuing the servers with a bmi-tcp and a bmi-tcp-alternate address work? ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Labs, IL USA B29D F333 664A 4280 315B _______________________________________________ Pvfs2-developers mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-developers
