Ubuntu 10.04 - How to get partitions aligned correctly?

post #1 of 2
Thread Starter 
Hey guys (I'm really desperate frown.gif )

First off, I'm running Ubuntu 10.04 LTS.
I have 5 x 2TB WD20EARX HDDs and I'd like to create a Raid 5 array.

Now if I use disk utility, I can create a RAID array's from there. However, every time I choose to do so I then get a warning message in Disk Utility for every disk in my array saying "The partition is misaligned by 3072 bytes. This may result in very poor performance. Repartitioning is suggested."


I know it's got something to do with the sector sizes as WD uses 4k sectors on these drives. But I still don't know how to solve this problem.

Any ideas what I could do to get my partitions aligned correctly?

Thanks in advance.

Use the WD partitioning tool as advised on the label on the harddrive, or Google how to use parted to properly align your partitions, eg. [g]how to align 4k partitions parted[/g]
