Thanks nate.
Right now I am not concerned with the load balancing. I have few cluster nodes and if I run mode1 , then the failover time may lead to cluster timeout. I have not tested it yet but I will do it. So if the failover time from active to backup is very small and in miliseconds my cluster can afford that and I will stick with mode 0. Is there a way to change this time/durartion ? Thanks Paras.

Nate,
Thanks for you input. 802.3ad seems better but I am not in a position to terminate both links in the same switch or same stack. What about mode 6?
I have a NFS cluster running mode 6 with two systems, it works ok, been running for a bit over a year now. Each system has 4 NICs, and 4 IPs(load balancing done mostly via round robin DNS).
The systems run CentOS 4.x, they are basically appliances everything comes pre-configured by the vendor.
So I can say it can work, and does work when properly configured, though I would not use it myself. The vendor has since moved away from this and is going with 802.3ad for better standards compliance.
