adding a drive to raid 0 and LVM without data loss
Currently I have 2 1TB WD-black hdds in Raid 0 and 1 2TB WD-Green.
Everything is setup in LVM and formatted with ext4.
I want to eventually expand my storage and want to buy 2 more 1TB drives, put them in raid 0 and add them to my LVM. Or buy another 2TB drive, create a raid with my existing 2TB drive and add it to the LVM.
I have also been considering raid 5 for a little more reliability.
Is it possible to do this without losing data? My main system is on another 200GB hdd.
Also I am using mdam raid for the raid. Not hardware raid.
