When are diskless compute nodes inappropriate?

Okay, I'm convinced by the arguments in favor of diskless compute
nodes, including cost savings applicable elsewhere, reduced power
consumption, and increased reliability through the elimination of
moving parts.

With all the arguments against disks, what are the arguments in favor
of diskful compute nodes? In particular, what are the situations or
types of jobs for which a cluster with a high percentage of diskless
nodes is contraindicated?

I look forward to learning from the list's collective wisdom.
