Discussion

File system journaling, or logging, can allow reconstruction of file system data after a system crash preserving the integrity of data that may have otherwise been lost. Journaling file systems typically do not require consistency checks upon booting after a crash, which can improve system availability. Some file systems employ other mechanisms to ensure consistency also satisfying this requirement.

Check Content

Verify local filesystems use journaling.
# mount | grep '^/dev/' | egrep -v 'type (ext3|ext4|jfs|reiserfs|xfs|iso9660|udf)'
If a mount is listed, this is a finding.

Fix Text

Convert local file systems to use journaling or another mechanism ensuring file system consistency.
