I attached two identical hard drives to my linux machine. Then using gparted I formated the first 1024 mb at the beginning of each drive as linux swap space.

Then I went into system->administration->disk utility. In there I went to file->create->RAID array. I selected the remaining space in each of the two identical hard drives and created a striped raid array.

After the array was created, a warning message appeared. It said "The partition is misaligned by 522240 bytes. This may result in very poor performance. Repartitioning is suggested."

What do I do now? As far as I can tell, the partitions are identical.

If you are building a raid array in Disk Utility, you need to manually create partition tables on your disks before you create the array in order to avoid the misalignment error.
