Re: [gentoo-user] nfs warning: mount version older than kernel

[Bryan Whitehead]

first, make sure portmap is running on both machines. I'm sure it is but 
check anyhow. Also make sure they are not wildly different versions. Do 
the same for util-linux package.

run 'rpcinfo -p' on each machine and copy/paste the output. I have a 
feeling one kernel has NFS v3 and another has NFS v4...
