Okay. So what are the options for dealing with swap?
a) Have swap on sd0b or sd1b
This means it will be "bad" if that disk fails, and I want the
system to keep
running. It'll not run at all, right?
b) Have swap on raid0b
This means the above issue is in effect, but swapping will work if one
of the disks fails, and the RAID is running in degraded mode, right?
There are issues with (b) where it suggests you put a 'b'
partition on the
underlying disks. Is this for the crash-dump code? Can crash-dumps not
happen to a raid device? I guess I need to re-read the aforementioned
document to check, but any comments from those who've been here
before would be welcomed. Thanks!
