When I search around for example RAID1 installations, it seems that admins tend to place their swap partition under RAID1.
To me, it is more intuitive to have two disks, each with a large partition for use by RAID1 and the system partition and with a smaller partition for swap, outside of the RAID array.
What is the worst-case-scenario if I lost a disk and effectively half of my swap space while the system is running?
Should I expect to see a performance increase or decrease while mirroring a swap volume vs having two separate swap volumes outside of RAID?
If swap should be mirrored, does it make more sense to give swap its own RAID1 array, or does it make more sense to partition one big RAID1 array with LVM?
(Note/4. I'm not sure if mdX can be partitioned without LVM, but the debian installer leads me to believe that it cannot)
