Makes sense, does NFS support sharing such large volumes? I suppose that will depend on both the server version of NFS and the client, but it's something you need to keep in mind. I think for a large file file system xfs is probably what you want, but you will want to run CentOS 64-bit with the 8k stacks to see it's full robustness and stability. Some people think xfs is good everywhere, but that's simply not true, I always recommend putting the OS on ext3 and then choosing the file system for your application data that best suits the application. Basically you have ext3, jfs, xfs, gfs and ocfs, the last 2 being clustered file systems. ext3 is good because it is widely supported and performs well under mixed work load, jfs is supposedly excellent if you have a lot of small files like a mail/news server, xfs for large files and of course gfs or ocfs for clusters that need simultaneous file system access from multiple nodes (but they are slower due to locking overhead). If you have volumes over 8TB then you really need to use either jfs or xfs depending on the application and if you are using xfs I highly recommend you run 64-bit for stability reasons. -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
