4d Select Do Not Format , then select Linux LVM (0x8E) from the list of file system IDs.
4e In Size , set the cylinder End Value to 5 GB or larger, depending on the combined partition
size you need to contain your system and swap volumes. You are creating a primary
partition that becomes the EVMS container for these two volumes that you create later in
this procedure.
IMPORTANT: Do not make the system partition larger than necessary. The remaining
space on the system disk can be used to create data volumes that are managed by EVMS.
To determine the size you need, consider the following recommendations:
Š
If you intend to create data volumes on the same physical disk, you must leave
unpartitioned space available.
Š
Set aside 128 MB or larger for the swap partition.
Swap management is different for Linux kernel 2.4.10 and later. How much swap to
add depends on the RAM size, the tasks that are planned for the system, and whether
you want to make more virtual memory available than the RAM provides.
Some swap (at least 128 MB) is good in order to minimize the risk of losing data
when active processes run out of RAM space. Swap is not required for systems with
more than 1 GB of RAM. You must have at least 1 GB of virtual memory (RAM plus
swap) during the install, but if the swap is more than 2 GB, you might not be able
install on some machines.
4f Click OK .
The partition appears as a logical device in the devices list, such as
/dev/sda2
.
5 Modify the volume management type from LVM to EVMS for the second primary partition
you created in
Step 4 as follows:
5a
At the bottom of the page, click EVMS .
5b In the EVMS Configuration dialog box, click Create Container , then select the LVM
partition created in Step 4 .
5c In the Create EVMS Container dialog box, specify the container name (such as system ),
then click Add Volume to create the
lvm2/ system
container, where
system
is the
container name.
5d Click OK .
The EVMS Configuration dialog box now displays the
lvm/ system
container you just
created, its size, and free space.
6 In the EVMS Configuration dialog box, create the
swap
volume in the
lvm2/ system
container as follows:
6a From the EVMS Container drop-down menu, select
lvm2/ system
, then click Add .
6b In the Create Logical Volume dialog box, select Format , then select Swap from the File
System drop-down menu.
6c Specify
swap
as the volume name.
6d Specify the size of the
swap
volume, such as
1GB
.
The
swap
volume should be at least 128 MB or larger. For more information, see Step 4e
on page 18 .
6e
Specify the mount point as swap .
