Chapter 7 Working with Disks and Volumes 93
Before running newfs, label the disk using the disklabel tool.
To format a disk:
$ newfs
For more information, see the newfs man page.
To format a disk to HFS+:
m Use the newfs_hfs tool in /sbin:
$ newfs_hfs
For more information, see the newfs_hfs man page.
Troubleshooting Disk Problems
To verify the physical condition and file system integrity of a volume, use the diskutil
or fsck tool (fsck_hfs for HFS volumes). For more information, see the related man
pages.
Managing Disk Journaling
A robust file system journaling feature is available to enhance the availability and fault
tolerance of servers and server-attached storage devices.
Journaling protects the integrity of the Mac OS Extended (HFS+) file system in the
event of an unplanned shutdown or power failure, and maximizes uptime by
expediting repairs to the affected volumes when the computer restarts.
Determining if Journaling Is Enabled
To see if journaling is enabled on a volume, use the mount tool.
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)
Enabling Journaling for a Volume
To enable journaling on a volume without affecting files on the volume, use the
diskutil tool.
Important: Always check the volume for disk errors using the fsck_hfs tool before you
enable journaling.
