I can't do anything about problem #2, but problem #1 seems like it
might be resolved by using a node health check script.  The Warewulf
NHC project can be used in this role and has built-in checks for
making sure the root filesystem is mounted read-write and has not
errored out.  It can also verify that your filesystems haven't filled.

If you're interested, I'd be happy to help you with getting it set up
and working in your environment.
