I want a mirrored (raid-1) system which is fail-safe. I am not
interested in speed.
If you simply have swap striped over disks, then when a disk fails the
whole system
will come down because part of virtual memory does not exist any more.
If you can
run swap on a mirror when one disk goes down the other still holds the
information
and the system continues running until you decide to shut it down to
replace the
failed disk.
