Unfortunately tcp is often necessary with netapp, and rsize/wsize is set to 32k like he said. I run a few Oracle servers with shares on our netapp. We use tcp,noudp,rsize=32768,wsize=32768,hard,nointr That's from memory of course. We use rhel2.1/3/4 with netapp over gig-e. For now... Soon will be fiber. On 3/5/07, Craig White wrote: > On Mon, 2007-03-05 at 14:36 -0700, David wrote: > > I'm in need of some help.
