Hi,
NetApp support has suggested us aligning partitions to improve
performance, in short: starting sector must be divisible by 8. How can I
move the start point in a misaligned partition -in production, with
ext3- under Linux?
A screenshot with a misaligned (start=63s) and aligned (start=64s)
partition is available at:
http://filesocial.com/lkwvvn2
(If anyone is interested in this topic, NetApp has a good document
explaining performance issues in misaligned partitions: "Best Practices
for File System Alignment in Virtual Environments", http://goo.gl/EkBw)
I have tried using parted "resize + move" commands, but when moving
start point a get this error:
(parted) resize
Partition number? 1
Start? [64s]?
End? [419425019s]? 419425018
(parted) move
Partition number? 1
Start? 65
End? [419425019s]? 419425019
Error: Can't move a partition onto itself. Try using resize, perhaps?
Using fdisk 'b' command in expert mode ('move beginning of data in a
partition') works, but it doesn't move the file system.. thanks!!
