# 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.
