You only need to provide the path to check here. Everything after
the first ! and before the second ! (if there is one) is passed to
the check command as $ARG1$. This means your command is expanding
to something like:

check_by_ssh -H 1.2.3.4 -C '/u/l/b/check_disk -p  -H 10.0.2.10 -C '...

Obviously that's going to confuse check_disk. It should look like
this:

  host_name            nfsserver
  service_description  DISK Remote
  check_command        check_remote_disk!/

This will then run "check_disk -p /" on the remote host, which
should do what you want.
