Certain workloads and certain AF drive firmware can really suck when there's a lot of read,modify,write done by the drive (internally) if the fs block is not aligned to physical sector size. I'm pretty sure parted and fdisk on CentOS 6 does properly align, whereas they don't on CentOS 5. Proper alignment is when the partition start LBA is divisible by 8. So a start LBA of 63 is not aligned, where 2048 is aligned and now common. -- Chris Murphy _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
