Red Hat Linux 8.0: The Official Red Hat Linux Customization Guide Prev Chapter 5. Managing Disk Storage Next Creating a Partition Warning   Do not attempt to create a partition on a device that is in use. Before creating a partition, boot into rescue mode (or unmount any partitions on the device and turn off any swap space on the device). Start parted, where /dev/hda is the device on which to create the partition: parted /dev/hda View the current partition table to determine if there is enough free space: print If there is not enough free space, you can resize an existing partition. Refer to the Section called Resizing a Partition for details. Making the Partition From the partition table, determine the start and end points of the new partition and what partition type it should be. You can only have four primary partitions (with no extended partition) on a device. If you need more than four partitions, you can have three primary partitions, one extended partition, and multiple logical partitions within the extended. For an overview of disk partitions, refer to the appendix An Introduction to Disk Partitions in the Official Red Hat Linux Installation Guide. For example, to create a primary partition with an ext3 file system from 1024 megabytes until 2048 megabytes on a hard drive type the following command: mkpart primary ext3 1024 2048 Tip   If you use the mkpartfs command instead, the file system will be created after the partition is created. However, parted does not support creating an ext3 file system. Thus, if you wish to create an ext3 file system, use mkpart and create the file system with the mkfs command as described later. mkpartfs works for file system type linux-swap. The changes start taking place as soon as you type [Enter], so review the command before executing to it. After creating the partition, use the print command to confirm that it is in the partition table with the correct partition type, file system type, and size. Also remember the minor number of the new partition so that you can label it. You should also view the output of cat /proc/partitions to make sure the kernel recognizes the new partition. Formating the Partition The partition still does not have a file system. Create the file system: /sbin/mkfs -t ext3 /dev/hdb3 Warning   Formatting the partition will permanently destroy any data that currently exists on the partition. Labeling the Partition Next, give the partition a label. For example, if the new partition is /dev/hda3 and you want to label it /work: e2label /dev/hda3 /work By default, the Red Hat Linux installation program uses the mount point of the partition as the label to make sure the label is unique. You can use any label you want. Creating the Mount Point As root, create the mount point: mkdir /work Add to /etc/fstab As root, edit the /etc/fstab file to include the new partition. The new line should look similar to the following: LABEL=/work /work ext3 defaults 1 2 The first column should contain LABEL= followed by the label you gave the partition. The second column should contain the mount point for the new partition, and the next column should be the file type (for example, ext3 or swap). If you need more information about the format, read the man page with the command man fstab. If the fourth column is the word defaults, the partition will be mounted at boot time. To mount the partition without rebooting, as root, type the command: mount /work Prev Home Next Managing Disk Storage Up Removing a Partition
