> I'm not sure what causes it, but there seems to be an effect where btrfs loves you or hates you and few people with mixed experiences regarding data loss.

I tried, I really tried to like btrfs.

On the servers/workstations I’ve had few serious issues, but a few “gotchas” you need to know to keep things running smoothly.

On every laptop I’ve had, I’ve had btrfs fail on me. Repeatedly.

So I gave up on it. ZFS for me these days.
