Ah that explains it. Don't use parity with btrfs (i.e. RAID5/6). If you really want that, that's a good reason not to use btrfs.

- matheusmoreira 6y agoBecause of the write hole, right? I've been avoiding btrfs because of that issue. Multiple copies are too wasteful and the parity implementation isn't perfect. Hope it gets fixed soon.
- zrm 6y agoThat was recently fixed in mdadm. You can now specify a journal device (--write-journal) which closes the write hole. I don't see any reason btrfs couldn't do something equivalent.
