[lustre-discuss] Remove failnode parameter

--erase-params should remove everything, but you have to set the other
ones (e.g. --mgsnode) again. If you don't want to have any --failnode,
just leave that one out. At least this is how it should work. If not,
you could post the exact command line and the output of the tunefs
