I don't know why you'd want to beta test a filesystem with your data.
- moqmar 4y agoYou don't, but you can still use it. Btrfs is stable, it's just the feature for RAID 5/6 that's explicitly marked experimental and potentially dangerous with known architectural issues. There was a time when that was a bit unclear, but now they're really straightforward about that: don't use RAID 5/6 and you have a rock solid file system.
- happymellon 4y agoAnd even then, RAID 1 does 95% of what people are looking for with RAID 5/6.
- tadfisher 4y agoRAID10 could also be a decent compromise, so long as you understand how it's implemented in BTRFS.
- happymellon 4y agoHow would RAID10 be a decent compromise compared to RAID1? RAID1 on 3 disks would give you two copies of the data spread over multiple disks. BTRFS lets you pick more copies of the data, essentially giving you RAID6.
