Gary,

The Hole might be big, but you might not need to spend anymore money.  If
you are already NOT using ldev1 for the databases, and you should not be
using it for anything other than system things anyway, for performance
reasons; then there already exists a split in the disc usage.  All that
making a separate volume would do is make that split more structured and
force the system to adhere to it. (It also increases the recoverability of
the system)

If you are using ldev1 pretty heavily for other things than system
tasks...well, good luck.  You end up paying one way or another.  Either you
get by on shoestrings and you spend a good amount of time, (which can be
related directly to $'s), recovering and you risk loosing some transactions
OR you spend a little money upfront and/or shuffle things around a little in
order to make things fit into a better, more recoverable running model.
