There is a lot of information, but also, I suspect there is a lot of disagreement. One thing that I could not find a definitive answer on was the question of whether or not to mirror swap.
There are articles that propose mirroring partitions independently (rather than the entire disk), and not mirroring swap, but adding two swap partitions with equal priority. On the other hand, there are people who point out that in the event where one of the disks in the mirror dies, the machine may cease to function, because a part of its "memory" will have disappeared. However, making swap part of the mirror opens a whole new can of worms. For instance, could there be a deadlock possibility (for example after a suspend/resume cycle) where mdadm is waiting for something which is swapped out onto swap which is mirrored?
It would be nice to have a discussion among people who have experience with all of this.
