I'm setting up an unraid server in a proxmox vm. Currently, I have 6 hds - 4TB x 2, 8TB x 2, 10TB x 1, 12TB x 1 and these drives are in a windows system on a stablebit drive pool. One of the 4tb drives I will remove going forward due to some errors indicating its about to fail soon.
Part of the new server migration includes installing a new 12 TB and new 14TB drive the latter of which I would like to be parity so I can try to over time move to mostly 14TB drives. I will pass through an lsi hba card and connect the drives to it.
What is the best way to migrate over from the drive pool and start moving the drives over? Is there a way to start moving the data and then enable the parity drive once I have enough drives in the pool to copy all the remaining data?
