I'll bite.

Apparently I tried this on Veritas volume manager
about 4 years ago on an index tablespace on a raw
Veritas volume.  While it seemed to work, I checked
with an experienced sys admin and he immediately tried
to strangle me over the phone.  He said that this is
definitely not supported.  A raw volume cannot be
resized.  The proper way to do so was to drop the
volume itself and recreate it.

He asked me to drop the index and re-boot. 
Fortunately things came up clean.  I was able to drop
the volume and rebuild a new volume.

But in short, what I've been told is that this is not
a supported operation.
