I.e., edit your /etc/fstab find the UUID for your drives and add/replace existing options /dev/sdXX /opt ext4 defaults,data=writeback,noatime,nodiratime 0 0Įnsure you have used tune2fs to turn on writeback mode BEFORE you edit your fstab file and BEFORE you reboot. To squeeze even more performance add fstab options: data=writeback,noatime,nodiratime This mode will typically provide the best ext4 performance. A crash+recovery can cause incorrect data to appear in files which were written shortly before the crash. This mode provides a similar level of journaling as that of XFS, JFS, and ReiserFS in its default mode - metadata journaling. In data=writeback mode, ext4 does not journal data at all. tune2fs -o journal_data_writeback /dev/sdXX As result old data may appear in files after a crash and journal recovery. Data may be written into the main filesystem after its metadata has been committed to the journal. Note that it happens at cost of reliability as it disables journaling for writing data.
