If we failed to write metadata buffers to the journal space and succeeded to write the commit record, stale data can be written back to the filesystem as metadata in the recovery phase. To avoid this, when we failed to write out metadata buffers, abort the journal before writing the commit record. We can also avoid this kind of corruption by using the journal checksum feature because it can detect invalid metadata blocks in the journal and avoid them from being replayed. So we don't need to care about asynchronous commit record writeout with a checksum. Signed-off-by: Hidehiro Kawai <hidehiro.kawai.ez@hitachi.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> |
