[olug] software raid advice - swap?

[Ryan Stille]

I'm setting up software raid (RAID1) on CentOS/RedHat. I've got two scsi 
drives I'm going to mirror as the / mount point.  What should I do about 
swap space?  I could place it on one of the scsi drives, but if that 
drives fails what happens?  Bad stuff I imagine, so why even have raid 
if the system is going to fail when the drive does?

I believe I could create two swap partitions, one on each drive, and the 
OS would use both at the same time (based on some stuff I read).  But 
there is still a good chance when a drive fails you're going to crash 
because there will be stuff swapped into that swap partition.

The other option I'm thinking is to create the swap partition as another 
raid device, mirrored on both drives.  I'm not sure thats possible.  
Whadda think?
