Topic: [closed] RAID Alignment & Partition Starting Offset
These days, I'm using more and more SAN based storage. The shared environments for disk storage make it a bit more concerning that all the RAID configurations are set to the most ideal settings for performance. I did not worry about this as much with the local RAID storage.
The trend toward virtualization has made this even more relevant.... all of which brings me to the point & feature request:
When a partition is resized with GParted, the partition starting offset is adjusted from the previous configuration! If one has gone through the effort to align the partition with RAID, the use of GParted will remove the adjusted partition starting offset. The result is that the effort to align the partition with the RAID is destroyed, and the partition is put back to the default (unwanted) setting.
For a short guide on setting disk alignment, partition offset from network appliance, and VMware ESX product, have a look here: http://media.netapp.com/documents/tr_3593.pdf
Feature Request #1: GParted should look at partition starting offset and not change it.
Feature Request #2: GParted should allow modification of partition starting offset.
Even with this issue, GParted is a fantastic utility!
