You can also edit free space as represented in the graphical display to create a new partition within
that space. Either highlight the free space and then select the
Edit
button, or double-click on the
free space to edit it.
•
Delete
: Used to remove the partition currently highlighted in the
Current Disk Partitions
section.
You will be asked to confirm the deletion of any partition.
•
Reset
: Used to restore
Disk Druid
to its original state. All changes made will be lost if you
Reset
the partitions.
•
Make RAID
:
Make RAID
can be used if you want to provide software RAID redundancy to any
or all disk partitions. It should only be used if you have experience using RAID. To read more about
RAID, please refer to RAID (Redundant Array of Independent Disks) in the Official Red Hat Linux
Customization Guide .
To make a RAID device, you must first create software RAID partitions. Once you have created
two or more software RAID partitions, select Make RAID to join the software RAID partitions
into a RAID device.
3.12.3. Partition Fields
Above the partition hierarchy are labels which present information about the partitions you are creat-
ing. The labels are defined as follows:
•
Device
: This field displays the partition’s device name.
•
Start : This field shows the sector on your hard drive where the partition begins.
•
End
: This field shows the sector on your hard drive where the partition ends.
•
Size
: This field shows the partition’s size (in MB).
•
Type
: This field shows the partition’s type (for example, ext2, ext3, or vfat ).
•
Mount Point
: 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 will be 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.
•
Format
: This field shows if the partition being created will be formatted.
3.12.4. Recommended Partitioning Scheme
Unless you have a reason for doing otherwise, we recommend that you create the following partitions:
•
A swap partition (at least 32 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. The size of your swap partition should be equal to twice your computer’s
RAM, or 32 MB, whichever amount is larger, but no more than 2048 MB (or 2 GB). In
Disk
Druid , the partition field for swap should look similar to the following:
Swap hda6 64M 64M Linux swap
For example, if you have 1 GB of RAM or less, your swap partition should be at least equal to the
amount of RAM on your system, up to two times the RAM. For more than 1 GB of RAM, 2 GB of
swap is recommended. Creating a large swap space partition will be especially helpful if you plan
to upgrade your RAM at a later time.
•
A
/boot
partition (50 MB) — the partition mounted on
/boot
contains the operating system kernel
(which allows your system to boot Red Hat Enterprise Linux ES), along with files used during the
bootstrap process. Due to the limitations of most PC BIOSes, creating a small partition to hold
