What are you looking to gain from using Btrfs on an NVR system? It doesn't sound like any of its prime-time features -- such as snapshots, checksumming, compression or reflink copying -- are a must for a bulk video recording scenario. And even if you don't need or use those features, you still pay the price for having them, Btrfs can be 2x to 10x slower than its simpler competitors: https://www.phoronix.com/scan.php?page=article&item=linux418-nvme-raid&num=2 If you just meant to use its multi-device support instead of a separate RAID layer, IMO that can't be considered prime-time or depended upon in production (yes, not even RAID 1 or 10). -- With respect, Roman
