Aw: Re: session trunking with NFS
Hi,
today i tried it, but it didn't work:
on my nfs-test system I use the 2x1GB interfaces
showmount -e <NFS-IP1>
and
showmount -e <NFS-IP2>
shows me the exports
so now i mount the nfs-share on a server with 10G Interfaces(bond), when i mount it with the second NFS-IP, I got an error "mount.nfs: mount(2): Device or resource busy"
Did I something wrong?
best regards
Stefan

The RFC[1] said NFSv4.1 has the capability for sessiontrunking to speed up the performance/throughput, so my question is how can I archiv this? How to configure the NFS-server and how to mount it on the client-side? There is no hint in the manpage for this.
