My question is a bit broader than the question title, but here is my situation: I have Synology Hybrid Raid (SHR) built on 2 x 2TB drives. I want to migrate to a software-RAID on a homegrown linux machine. My current plan is backup the SHR remotely, setup a RAID6 with LVM using 3 x 2TB drives, and then restore the backed-up directories to the new RAID.
In the future, if I want to add more drives, is it possible to dynamically expand the RAID6? Are there any good articles explaining the relationship between RAID6 and LVM? This machine will be for my own person use and limited web traffic, so drive fault tolerance is more important to me than speed.
