Linux question regarding NFS

[chopramanish1988]

Hello Everyone,

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



Thanks
Manish

Having your root file system on another system is inherently dangerous, and I think you are correct that when the link goes down, you lose it. When you boot, chroot to a file system in ramdisk if you don't have a physical drive. You can boot with a root fs image that is mounted into RAM. Then when you temporarily lose your network connection, you will still have your basic file system and commands, and then when it comes back up, links will be there for you.
