Hi List, I`m trying to build a cluster storage with commodity hardware in a way that the all the data would be on > 1 server. It should have the meet the following requirements: 1) If one of the servers goes down, the cluster should continue to work with rw access from all clients. 2) Clients that mount the storage should not be part of cluster (not export any disk storage) - I have few servers with huge disks that I want to store data on (currently 2 servers, maybe more in the future) and I want to storethe data only on them, the rest of the server should just mount and use that storage with the ability to continue operation if one of the two storage servers goes down. 3) More servers should be able to join the cluster and at given point, expanding the total size of the cluster, hopefully without rebuilding the storage. 4) Load balance is not a issue - all the load can go to one of the two storage servers (although its better to be balanced), the main goal is to have redundant storage Does ocfs2 meet these requirements? I read few howtos but none of them mentioned my second requirement (only some of the servers to hold the data). Are there any specific steps to do to accomplish (2) and (3)? I`m using Ubuntu 6.06 on x86. Thanks!
Appears what you are looking for is a mix of ocfs2 and nfs. The storage servers mount the shared disks and the reexport them via nfs to the remaining servers. ubuntu 6.06 is too old. If you are stuck on Ubuntu LTS, the next version 7.10 should have all you want.

Is there any cluster NFS solution out there? (Two NFS servers sharing the same filesystem with distributed locking and failover capability) Regards, Luis Sunil Mushran <Sunil.Mushran@oracle.com> wrote: Appears what you are looking for is a mix of ocfs2 and nfs.
