When copying content to a Xsan volume, on occasion the copying will halt for some time and then continue. I have a feeling that there is an issue wit the network. I don't see anything on the console logs on either the client or the MDC. Is there any way to see if the network is causing the stall? Before you ask, I do have a separate network with a separate switch for the metadata network.

While I don't think it is an issue, the following appears on the fsmpm logs on both clients:

For those looking for the answer, it appears that having one of the controllers set to 2gb/s while another was set to 4gb/s was the issue. I didn't know I even had it like that, but I did.
