problem with nfs mount on boot

[Frank DiPrete]

I've been seeing a strange problem common to a bunch of servers.

The servers need to nfs mount storage on boot but half of the time the 
mount fails with "server not available" but right after I can mount the 
storage manually.

I took the mount out of fstab and wrote a delay in rc.local (15 secs) 
before mounting and that helped but has still not solved the problem. I 
could loop and wait but I'd rather figure out what the problem is.

I am using bonded interfaces - ifenslave-2.6 on debian systems with 
e1000 nics into cisco gig-e switches.

bonding is configured as failover links (mode 1) using mii for link 
detect polling every 100m secs. For this test config the nfs server is 
also a debian (etch) system.

My next guess is the updelay parameter but it's a guess.

Anybody else run into a problem mounting nfs on boot?
Just looking for areas to look more closely,

Thanks
