Hi, Dale, It sounds like you’ve found where to set the `vers=4` option. If that doesn’t work, it’s possible that the ROACH2s don’t support NFSv4. If that's the case (I’m not sure it is), then you may have to look into exporting the root filesystem via NFSv3 instead.
I always have to double check the MTU configuration on the NFS server’s network interface. I think setting it to larger than 1500 won’t work for the ROACH2s. I’m curious to know what the solution ends up being!
