NFS performance trouble: with infiniband gets stacked with many users?

  • 772

I have a RAID system on A server and similar configuration on B server-both with Scientific Linux 5.5. They are connected with infiniband and RAIDS from A are mounted with NFS to ServerB. Now when the users are accessing A-Raids via B-Server, the network getting stacked already with 2 rsyncs. What is the reason? Can I some how bench it and tune the NFS?

    So you've got mirrored NFS servers and some mechanism for keeping them in sync using rsync? This is a recipe for problems. It also implies that you've got a homegrown script trying to keep it all working. Certainly NFS is the last of your problems.

    Ideally, you should consider using a shared storage backend with a cluster filesystem e.g. GFS). Alternatively you might consider something like AFS (which manages its own replcation and tells you when problems arise).
