I've installed a new RAID array in my home server and the disks are using 4KB sectors instead of the traditional 512 byte sectors.
How do I properly align the partitions to this disk? YaST partitioner shows "cylinders" and I can not come up with a formula to convert cylinders to sectors. My understanding is since 8 x 512 = 4096 (4kb) all I need to do is ensure that my partitions are aligned to multiples of 8 sectors.
The installer and yast-partitioner auto-detect drive topology in openSUSE11.3 (and newer). Since you mention raid, the alignment should not only be to a 4KB sector, it should be to a full raid stripe, but not raid is supported yet I suspect. Look in /sys/block/*/queue for various topology data. (/sys is a kernel interface, not actual files). If partitions are not auto-aligned, please file a bug. Prior to 11.3 you're on your own.
