Given one of the goals of RAID is to keep the system running when a
drive fails, what happens when a drive containing swap croaks?
Your available swap space would be reduced, doesn't cause the system to
fail.
Actually it can cause the system to fail, depending on what was swapped to
the device that failed. At the very least applications that had pages
swapped to the failed swap device would crash.
They won't crash... because they can't resume execution...
a process which hits a page that's swapped to a device
which no longer functions will simply halt on I/O, waiting
forever (literally) for the next page of code or data to
get swapped back in.
On the other hand, if the kernel has swapped out some data,
and can't bring it back, THAT can cause a system crash.
