Linux question regarding NFS
I have a question regarding NFS. I have a PXE booted linux setup via a ethernet network interface and the root file system is mounted from a another
linux host using that same ethernet network interface. When i try to change any ring parameters [using ethtool -G] associated with that ethernet interface link goes down
and comes up back. But my system becomes unresponsive. I think while link goes down and up rootfs will be lost.
can anyone please tell me is this expected or not? OR do we expect that rootfs would be mounted again and system should behave normally as it was before
