misaligned raid partition in Ubuntu 10.04

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.

0	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. link answered 23 Aug '10, 13:41 jeremy ♦♦ 1.0k●1●5●16 accept rate: 37%
