Why? Shared disk means shared point of failure, and poor redundancy
against a variety of non-total failure conditions  (data corruption,
etc). Add the synchronization costs to the mix, and I don't see the appeal.

I think clustering _in general_ is becoming a big issue, but I don't
really see the appeal of shared-disk clustering personally.
