| # Set the NOCOW attribute for directories of journal files. This flag |
| # is inherited by their new files and sub-directories. Matters only |
| # for btrfs filesystems. |
| # |
| # WARNING: Enabling the NOCOW attribute improves journal performance |
| # substantially, but also disables the btrfs checksum logic. In |
| # btrfs RAID filesystems the checksums are needed for rebuilding |
| # corrupted files. Without checksums such rebuilds are not |
| # possible. |
| # |
| # In a single-disk filesystem (or a filesystem without redundancy) |
| # enabling the NOCOW attribute for journal files is safe, because |
| # they have their own checksums and a rebuilding wouldn't be possible |
| # in any case. |
