Any NFS gurus?

[TheExcession]

I have two Linux boxes, each have two Ethernet Cards.
Box 1 connects to box 2 via two switches for redundancy.

Box 1 eth0 - Switch1 - Box2 eth0
Box 1 eth1 - Switch2 - Box2 eth1

Now if I export a share from Box 1 and mount it from Box 2 - I need to specify the IP Address of eth0 for the export & mount.

If Switch 1 goes down then the mounted share is lost as eth0 isn't there any more.

Is there a way to to get the mount to work across either interface?

Box 1 and Box 2 each have a virtual IP Address behind the eths and we use OSPF to control the routing - but NFS doesn't seem to work with Virtual IPs.

Anyone got any bright ideas?

Edited to say - we need rw access as well so I can't see using a replicated share working.

Not really

I'm not allowed to patch our 'live' systems.

We are looking at SCP instead which hopefully will circumvent all this NFS nonsense...

If you were using the automounter you could try specifying multiple servers and use the "soft" option (although I don't know if it would work). With fixed mounts I think you are stuffed.
