MDC. And CP IND shows the MDC hit rate that you get from that. One way
to approach this is to take a bit off and see whether that really
makes a hit rate much worse, etc.

remainder as spool again, provided you stick it back in the same

sure
that portion is dumped as well.
For large virtual machines you will need to prepare a dump volume and
dump onto that.
Personally I would also play a bit with CP TRACE to understand where
the loop is, and if it's around a spinlock try to see who's holding
that.

limits for MDC fairly low (I think I have even seen it work with 0M

paging it.

discussing here is one reason, but
there are other reasons.
Why are PDS's not cached?
VM paging is not eligable for MDC, that's just for virtual machine
I/O. But the paging routines use other techniques to exploit the
hierarchy in storage and drive I/O efficiently.

This sounds like accepting the requirement to

noticed the problem earlier when it had no disk at all.
And for those that share /usr in R/O fashion it makes sense to use 'R'
rather than 'RR' to make sure your Linux server will not try to do
