I have 2 questions:
1. Should I defrag HDDs on my NAS? They are on btrfs. If yes, how often? I read that I should delete all snapshots before defrag and recreate them afterwards. What is the most efficient way to recreate snapshots? How to handle immutable snapshots if I have any?
2. My current array: 3x ST16000NT001 on SHR. I have only 1 empty bay. Planning to add another ST16000NT001, but the model is out-of-stock. Closest alternative is ST18000NT001. So, if I opt for 2x 18TB (so I won't waste the 1.8TB), I need to remove a 16TB. Would it be wasteful to use that 16TB drive as an external backup destination for my NAS?
Thanks.
