Create an XFS filesystem on the MDS, and export it. If the client has blkmapd running (on Debian it needs to be started manually) it will use pNFS for accessing the filesystem. Verify that using the per-operation counters in /proc/self/mounstats. Repeat with additional clients as nessecary. Alternatively set up a simple iSCSI target using tgt or lio and connect to it from multiple clients. Which sounds reasonable to me, but I haven't tried to incorporate this into my regression testing yet. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
