SUSE Linux 10 data partitions

Data partitions is a generic term for partitions that are formatted as a filesystem and in which both the system and its users can store data. The partition designated as the root filesystem is a special case of a data partition because it is required in order to boot a Linux enterprise system.

The preceding sections explained how to create the swap and root partitions that must be present to successfully boot a Linux enterprise system. However, you can also create other data partitions, format them as filesystems, and specify their mount points during the installation process. On Linux enterprise systems, a mount point is simply a Linux directory through which a filesystem is made available to the system, known as mounting that filesystem. Using regular directories as mount points is a clever part of the design of Unix and Linux. If you run out of disk space on a given partition, you can add another disk to your system, create data partitions there, copy the data from existing directories to those partitions, and then mount the new partitions on the directory where the data was originally located, effectively increasing the amount of storage available to an existing system.

Today's larger disks make it attractive to create other data partitions. You have several reasons to consider creating multiple data partitions on today's disks:

  • When you boot a Linux enterprise system, the system checks the consistency of each of its filesystems. Checking the consistency of
