Ok.  I will do this.

My original strategy was to:

1. create a ~2.8TB raid6 array out of 8 500GB drives

2. just make one big monster partition of the entire 2.8TB under
"partition" in sysinstall

3. under "label" in sysinstall, divide that into /, swap, /var and two
large data partitions, neither of which exceeds 2TB (since snapshos have
trouble over 2tb)

do you think the above srategy is reasonable ?
