You might not have to give up on PVFS just yet, but it will take more hardware. You can set up PVFS servers in an active-active high availability config, and then when one server goes down, another machine will take over for it. This setup does require shared storage. Take a look at the pvfs2-ha and pvfs2-ha-heartbeat-v2 documents (in the doc/ directory) for more information. ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Lab, IL USA B29D F333 664A 4280 315B _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
