Running on hyper-v I'm using Ubuntu's Azure kernel. Today I updated to the latest 6.11.0-1012 version. After a reboot none of my NFS shares (running on a PetaSAN cluster) were mounting anymore. I had to revert to the previous 6.8.0 kernel to fix the problem. Does anybody have any clue/insight on what happened with the latest kernel and how I can update the kernel without losing my NFS mounts?
