I was trying some mount options from this answer, however, whenever, I have attempted using them I received this error when remounting:
mount.nfs4: mount(2): Invalid argument
mount.nfs4: an incorrect mount option was specified
When remounting, these are options that will are reported to be used by mount: "rw,noexec,remount,soft,intr,port=2049,sec=sys,lookupcache=none"
What is going on here? Are these options not supported by NFSv4?
