Managing Disk Journaling
Checking to See if Journaling is Enabled
You can use the mount command to see if journaling is enable on a volume.
To see if journaling is enabled:
$ mount
Look for journaled in the attributes in parentheses following a volume. For example:
/dev/disk0s9 on / (local, journaled)
Turning on Journaling for an Existing Volume
You can use the diskutil command to enable journaling on a volume without
affecting existing files on the volume.
Important: Always check the volume for disk errors using the fsck_hfs command
before you turn on journaling.
To enable journaling:
$ diskutil enableJournal volume

$ mount
/dev/disk0s9 on / (local, journaled)
/dev/disk0s10 on /Volumes/OS 9.2.2 (local)
