available in the graphical installation program.
To create an LVM logical volume, you must first create partitions of type physical volume
(LVM). Once you have created one or more physical volume (LVM) partitions, select LVM to
create an LVM logical volume.
19.3. Partition Fields
Above the partition hierarchy are labels which present information about the partitions you are
creating. The labels are defined as follows:
• Device: This field displays the partition's device name.
• Mount Point/RAID/Volume: A mount point is the location within the directory hierarchy at
which a volume exists; the volume is "mounted" at this location. This field indicates where the
partition is mounted. If a partition exists, but is not set, then you need to define its mount
point. Double-click on the partition or click the Edit button.
• Type: This field shows the partition's file system type (for example, ext2, ext3, or vfat).
• Format: This field shows if the partition being created will be formatted.
• Size (MB): This field shows the partition's size (in MB).
• Start: This field shows the cylinder on your hard drive where the partition begins.
• End: This field shows the cylinder on your hard drive where the partition ends.
Hide RAID device/LVM Volume Group members: Select this option if you do not want to view
any RAID device or LVM Volume Group members that have been created.
19.4. Recommended Partitioning Scheme
Unless you have a reason for doing otherwise, we recommend that you create the following
partitions:
• A swap partition (at least 256 MB) — swap partitions are used to support virtual memory. In
other words, data is written to a swap partition when there is not enough RAM to store the
data your system is processing.
If you are unsure about what size swap partition to create, make it twice the amount of RAM
on your machine. It must be of type swap.
Creation of the proper amount of swap space varies depending on a number of factors
including the following (in descending order of importance):
• The applications running on the machine.
