I wanted to thank everybody for the private replies on this topic.

The reason I'm re-installing is because of two years worth of fragmentation.
I decided it was time to defrag because some extremely heavy :RESTORE
activity of large databases (for the big Y2K conversion) had trouble finding
sufficient space.

Also, now that I'm running a bunch of fork()-ing POSIX stuff, I don't want to
have fork() start dying due to insufficient contiguous LDEV 1 free space.  So
I am re-installing MPEXL_SYSTEM_VOLUME_SET too, instead of just merely
storing, purging, and recreating just the non-system volume sets.

My checklist that I posted wasn't meant to be 100% exhaustive.  I was already
planning to do some of the things you suggested.  I do think I will change to
doing the :RESTORE ;DIRECTORY separately from the big restore of all the files.

Next week I'll post my actual checklist of what I wound up doing on Sunday.

Yes, I am aware of the various defrag products out there.  I actually demoed
Bradmark's DSM once.  It was a cool product, but not one that we could justify
spending scarce .edu dollars on.
