High Availability for NFS

Hello All,

I need to purpose a NFS solution for a project that I'm working on and the requirements must met:
  • The NFS solution must be based on Linux - no cost\licenses
  • No physical servers required - It can be deployed on VM
  • There is no need for shared disk like RHCS
  • The storage must be highly available

I'm open to any suggestions.
Thanks.

Why is that?
OpenFiler for example cannot be configured with those requirements?
What are the limitations?

Does GFS cluster also requires shared disk?

Yes it requres a shared disk i.e. isci it also requires block level access there are further requirements i.e.
a failed node must not become available  while another node is recovering the journal for the failed node

Andrew, I know but I want the NFS path to be HA so it will tolerate failure of server.

Linux Cluster (http://www.linux-ha.org/wiki/Main_Page) , or put the Linux Server on VMware HA.

Highly available always requires something being shared. This way if your compute node goes down then the remaining compute node still has access to the data.

Where would you run the (2) Linux VM's? If you run them on the same host and the host fails then you have no storage (you could use local storage on the host as shared storage). If you run the VM's on separate hosts then you need a third host with the (shared) storage. How do you intend to spend the budget that you have? You do have a budget right?

The solution that we've decided to use is GlusterFS.
No shared drive, cluster can tolerate failure of hosts without losing the data.
Can be virtual - yes
Need shared drives - No
Free - Yes
Fault tolerance and HA - Yes.
