Greetings all. I've just acquired a 4-port network card, and I
set it up so that the 4 ports are each assigned an IP address, and gave
all the IPs the name 'nfs' in DNS.
Now I hope to point all the NFS clients at server 'nfs', and do some
basic load balancing, while leaving the original address open for other
services.
My problem is that I haven't been able to weight the routes to the
subnet in question. I've been using iproute2 and have read numerous
documents online, but they all discuss multiple Internet gateways.
I hope to find a way to send traffic coming in on each of the 4
interfaces back out that same interface, so the load can be balanced
between them. Right now, all traffic goes out through the default
route with the lowest metric.
Eventually I also want to configure nfsd to listen only for connections
on that host name, so that the original ethernet interface is left open
for other services.
Does anyone have any suggestions, or comments, or criticisms? Anybody
konw how to do a thing like that?
First off don't assign separate IPs to each port on your four port card,
bond them into a single interface. That will simplify your config and
perform better.
Second, what sort of routing are you doing? If all the clients are on
the same subnet as the four port card you should not need routing.
Additionally if they are on the same subnet you should not be limited by
the speed of your gateway which may or may not be able to route at 4
Gb/s whereas your switch may actually have that sort of performaance.
Are the clients on a separate subnet and if so can you put them on the
same subnet?
