Is it possible to have a load-balanced solution for NFS?

I currently have 1 server for storing files for webusers to access... but with impeding increase in traffic, I wonder if it is possible to adopt a load balance solution?

depends what you call load balancing i guess, and also how the users come into the equation. the simplest way for real web users would probably just be a DNS round robin solution. if you have enough individual users and can resolve the server they go to to two different boxes then that *may* fit in well. other than that, check out the lvs project which can perform the load balancing generically. as a technology it's absolutely possible. i've not done it myself, but for simplicity if nothign else, you'd probably want to restrict NFS to use dedicated ports rather than relying on portmapper to do it for you. this would certanily make any troubleshooting about session persistence etc much easier.

I haven't tried this but you could try using balance + NFS (http://www.inlab.de/balance.html). It's available in most distro repos. Maybe something like this assuming you're using tcp only NFS:

/usr/sbin/balance -f 2049 nfsServer1:2049 nfsServer2:2049 ...

or you could try nfs4 with pnfs

please don't drag up dead threads, there was no need to resurrect this and it can get very messy and confusing when people don't notice the original times of the post.
