With the 10TB Red drives being on sale right now, I’m looking to upgrade the storage in my PR4100 from the 6TB drives in it now to 10s. I’d also be wanting to take the opportunity to encrypt the volume, since I missed doing that during the initial setup, so I can’t just do multiple RAID rebuilds and an expansion. I don’t have enough storage space elsewhere to offload the ~16TB of data I currently have on there. Has anyone ever switched back and forth between multiple sets of drives on the PR4100?
I do have an unused 4TB drive sitting around, so my plan would be to transfer 4TB of data from the existing array to that, shut down the NAS, swap in the 10TB drives, transfer the 4TB to them, shut down, swap back to the 6TB drives, and repeat until all 16TB have been transferred to the new array. I’m just worried that some configuration will be lost when swapping back and forth and that I might lose everything. Has anyone ever tried something like this?
