[ale] Topic ideas for November meeting

[Lightner, Jeff]

Funny.  Here we did that and were accused of "hiding disk space".    They couldn't see why you'd want to keep space in reserve until needed even though they were specifically asking for a new filesystem that we couldn't have built if we hadn't done it the way we did it.

+100!

I also always leave the bulk of the PVs unallocated until I know the usage pattern.  And even then I leave some for emergency resizing.
