Preparing Disks for Installing Mac OS X Server
When you perform a clean installation, the target disk or partition is erased and there
are several disk-preparation tasks to perform:
• Preserve any user data you want to save on the target disk or partition. See the
migration guide for information on migrating data and settings.
• In most cases, format the target disk using Mac OS Extended (Journaled) format. You
can also use Mac OS Extended or case-sensitive HFS+ format. Case-sensitive HFS+
format is useful if case-sensitive file names are important, as when you need to
support legacy UNIX applications on Mac OS X Server. All case-sensitive disks are also
journaled.
• Optionally, partition the target disk and set up one of the partitions as the
destination for server software. The minimum recommended size for an installation
partition is 4 GB.
Important: Don’t store data on the hard disk or hard disk partition where the
operating system is installed. With this approach, you will not risk losing data should
you need to reinstall or upgrade system software.
• Optionally configure the target disk for RAID mirroring, which creates a backup disk
that is used automatically if the primary disk isn’t available.
You can format a disk or partition as Mac OS Extended (Journaled) from the Installer
application and as Mac OS Extended from the Disk Utility application. To format a disk
or a partition as case-sensitive HFS+, use the Terminal application. For example:
1 Choose a Mac OS Extended volume (for example, /Volumes/MyHFSPlus) to convert to
case-sensitive HFS.
2 Open the Terminal application.
3 Erase and reformat the volume as bootable; in this example MyCaseSensitive is the new
volume name:
sudo diskutil eraseVolume "Case-sensitive HFS+"
MyCaseSensitive bootable /Volumes/MyHFSPlus
See the man page for diskutil and the command-line administration guide for
additional information on creating a case-sensitive HFS+ volume.
Instructions provided later in this chapter describe when to perform disk preparation
tasks.
