I've been vaguely planning on using btrfs in raid5 for my next storage upgrade. Is it really so bad?
Check status here. It looks like it may be a little better than the past, but I'm not sure I'd trust it.
An alternative approach I use is mergerfs + snapraid + snapraid-btrfs. This isn't the best idea for a system drive, but if it's something like a NAS it works well and
snapraid-btrfsdoesn't have the write hole issues that normalsnapraiddoes since it operates on r/o snapshots instead of raw data.It's affected by the write-hole phenomenon. In BTRFS case that can mean that perfectly good old data might corrupt without any notice.
