Steve and Benny, Thank you very much for your help! I have successfully set up a 3-node testbed and ran some benchmark since. Unfortunately, throughput results are very poor. I am running Steve's 2.6.33.5-112.2.2.pnfs.fc13.x86_64 kernel, and exported a 28GB ramfs from my DS to the MDS. I was able to achieve ~400 MB/s over NFS using iozone. I then proceed to run the same test from the pNFS client and got only 50 MB/s. After detecting that my test data had landed on both the MDS and DS, I assumed disk I/O on the MDS was the bottleneck. So I proceeded to rebuild the kernel with CONFIG_PNFSD_LOCAL_EXPORT disabled, but achieved only 6 MB/s afterward. Is this expected, or am I doing something wrong? Please let me know if I need to provide further information.
