Here are some important warnings about the cluster tools:

1) No native language support:

These programs do, in some cases, have to identify error messages in order
to be able to take appropriate action. No provisions have been made so far
for error messages in languages other than English.

2) Dependency on correct configuration of the nodes:

These programs must assume that the nodes are correctly configured so that
they can operate correctly. In particular, the shell configurations of the
root user on the nodes must not contain anything that would cause the root
shells to hold busy the mounts of filesystems other than the root itself.
