LVM and disk alignment questions.
So, I'm running RHEL 5.x (physical) and I have a few questions that I hope you can help me with.
Is it true that if I set /etc/lvm/lvm.conf : data_alignment_detection to '1', the LVM partition will automagically align itself on my pv even if the pv is misaligned?
As I have a number of servers that are using LVM for all partitions.
(RHEL 6, I believe, aligns all partitions to a number divisible by 8, is this correct?)
Another thing... Is it possible that anyone knows of, if I can realign the root partition on the fly? Or is the only way to boot into a live disc and realign from there? (physical and, or, virtual)
Thanks for your assistance, and I appreciate it a LOT.
