I have 2x 10TB 1x 12TB drives. I want to know if Proxmox will allow me to setup a raidz-1 with just one drive —> then move over a ‘drive-full’ of data --> then add a drive to the pool and repeat until all drives are in the pool.
I have 20TB of data with no redundancy and 32TB of drive space.
What Sgt said. Though I would say mirrors aren’t a bad way to go either. Once a vdev is in a pool, that’s it, you can’t get rid of it. You expand the pool with larger drives or another vdev. If you lose a vdev, you lose the pool.
