FC6 update DVD can't find swap

[Bill Davidsen]

Here's a "found it the hard way" warning, if you make your swap 
partition RAID-10 software RAID (for performance), the upgrade mode of 
the install DVD can't find the swap, and the "rescue" option doesn't 
like it either.

Performance of RAID-10 is better than RAID-1, and gives more space if 
you have >2 drives.
