While I can't share exact IO and stats I can tell you that it keeps up with netapp filers that consistently push 40-80MBit/second 24/7/365.=20 Be sure to do some research on kernel and hardware obviously and you should be good. I would be interested to hear of anyone else using GFS in an NFS implmentation. Shortly we will be moving some NFS servers to large storage arrays and we need all NFS servers to see the same filesystems for redundancy and scalability. From what I've gathered GFS is ready for primetime - I would love to hear how it works from a NFS perspective. -Brian ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
