Can you let us know when you found nirvana?

If the disk partially fails, operation of a cache engine would be
interrupted.  This should result in the router excluding this
particular cache engine from WCCP as a fail-safe mode.  If not, the
software needs a simple sanity check to shut itself down (forcing WCCP
into a "standby mode" for this cache engine entity to allow for a
"limp home" mode).  This has nothing to do with WCCP itself.

Of course.
