The clients refresh their knowledge of volume location every two hours. This can be forced with "fs checkvol". The UUID represents the file server, not the interface. Once a client determines that an interface is down it will stop using it. > When can I safely shutdown that interface and remove that network? If the file server supported changing its address list while running the answer would be in two hours. However, the file server does require a restart in order to register a new address list. > I'd like to do this without needing to move all the volumes on kelp to > another server.
