rtfo
This can be very useful if there is a comms issue with the filer, or perhaps with replication that you are having problems monitoring or troubleshooting.
Make sure the gateway or router in question is in “/etc/mdgateways”. Then run “rtfo start”.
“rtfo status” will show you the counters. Rtfo will periodically run a ping, so this counter will constantly go up. Probably best not to run this command constantly. If there are any errors detected, then further investigation would be needed maybe in conjunction with ifinfo
