[ale] Looking for recommendations on LVM + soft Raid on home server

[Lightner, Jeff]

Even with indirect connections you can have problems.  For example I've seen a few occasions where badly structured Oracle queries essentially selected all rows and filled up /tmp space.

Why Oracle uses /tmp space rather than its own assigned space is another battle entirely so don't ask.

If you have a lot of (irresponsible) users, I can agree with that
logic. Thankfully, I don't have to worry about very many people
directly connecting to the system. Most only connect to the services
provided by the system.

Keeping root (with /etc as part of root) separate from these other filesystems helps to keep from corrupting passwd and other files due to a full filesystem.
