Greetings, We are preparing to transition users from a Cray XT3 sytem to an XT4 system. In order to transfer the data between the two Lustre filesystems, we are looking at the possibility of having one system mount the other systems file system. This would allow data to be copied directly. However, we aren't certain if this will work. Its not clear to me that the current routing implementation will handle two portals networks. I can sort of see how we would define the ip2nets. However, in looking at the router lines, it looks like we will need to specify portal nids. It isn't clear to me how the system would distinguish a local portal nid from the same nid on the other system. Am I overlooking something? This is a temporary situation. We just need these mounts in place while we move the data. So, even a temporary work around may be useful. Thanks, --Shane
