for some unusual cases, this may not be the case. The device number will be used when re-ipling the
post-installed system.
17.14.2. Disk Druid's Buttons
These buttons control
Disk Druid's
actions. They are used to change the attributes of a partition
(for example the file system type and mount point) and also to create RAID devices. Buttons on
this screen are also used to accept the changes you have made, or to exit
Disk Druid
. For further
explanation, take a look at each button in order:
•
Edit
: Used to modify attributes of the partition currently selected in the
Partitions
section. Selecting
Edit
opens a dialog box. Some or all of the fields can be edited, depending on whether the partition
information has already been written to disk.
•
RAID
: Used to provide redundancy to any or all disk partitions.
It should only be used if you
have experience using RAID.
To read more about RAID, refer to the
Red Hat Enterprise Linux
Deployment Guide
.
To make a RAID device, you must first create software RAID partitions. Once you have created
two or more software RAID partitions, select
RAID
to join the software RAID partitions into a RAID
device.
17.14.3. 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.
17.14.4. Recommended Partitioning Scheme
Configuring efficient swap space for Linux on System z is a complex task. It very much depends on
the specific environment and should be tuned to the actual system load.
