General RAID question, mixing HDD's?
Ï'm a complete noob when it comes to RAID, but I'm building a server and want to use RAID on it along with LVM. I already have 2 3TB disks, but I want to migrate the OS and swap to an SSD, then use the 2 3TB along with some new disks in RAID. But I wanna get 4TB disks, would that work? Could I partision the 3TB's into 3 1TB partisions and the 4TB's into 4 1TB and mix them into one RAID? Or do I have to get all 3TB's or all 4TB's? And if it's possible to partision it like this are there any upsides or downsides to doing it that way?
