That's correct; the client would send a NULL RPC ping to each server in the list, and could failover to a network address that works better. > When all the addresses are for the same server though can this be used > for Read/write mounts? No - we can't tell that this is the case. Eventually, NFSv4.1 support will let us see multiple interfaces as grouped together. > Also, when DNS is used to resolve the server hostname, if it returns > more than one IP, will that be used as if I had listed each interface > separately? or do I need to list them all myself? Hmmm, I believe we can't see the multiple DNS results because we're going through the getXbyY() interfaces, so I think you have to list them separately - but you could try it. Rob T
