I would agree mirroring swap for a mission critical server. Otherwise it
would be an overkill, IMO.
If one of the non-mirrored swaps go down, then I will get a system crash.
So?
So you lose system availability. If you can stand this, then you don't
need availability.
Although swap going offline causing "a system crash" was a bit of an
overstatement. More likely, some user space applications would crash, allowing
a graceful system shutdown - once in 15 years or so.
What is of primary value of using RAID-1 for me is protecting my data against
disk failures.
As for continuous system availability, yes I am willing to trade it a bit on a
non-critical system for better disk utilization and performance.
