4c Select Primary Partition , then click OK .
4d Select Do Not Format , then select Linux LVM (0x8E) from the list of file system IDs.
4e In Size ( End Value field), 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.
IMPORTANT: Do not make the system partition larger than necessary. The remaining
space on the system disk can be used to create NSS volumes or native Linux volumes that
are managed by EVMS.
To determing how much space to use, consider the following recommendations:
Š
For your system volume, allow 2 GB (minimum) to 10 GB (recommended),
depending on the OES services that you intend to install.
Š
If you intend to create additional NSS volumes on the same physical disk, you must
leave unpartitioned space available.
Š
Set aside 128 MB or larger for the swap volume.
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 to have 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 to
install on some machines.
Š
The total size should be the size you need for your system volume plus the size you
need for your swap volume.
For example, if you have a 20 GB hard drive with 2 GB of RAM and plan to install all of
the OES services on the system volume, your system partition should be at least 11 GB.
The remaining 9 GB should remain as free unpartitioned space that can be used for NSS
volumes or other Linux partitions that you might want to create later.
4f Click OK .
The partition appears as a logical device in the devices list, such as
/dev/hda2
.
5 Modify the volume management type from LVM to EVMS for the second primary partition
you created in
Step 4 :
5a
At the bottom of the page, click EVMS .
Available partitions for EVMS appear as devices under
/dev/evms
, such as
/dev/evms/
hda2
.
5b In the EVMS Configurator, select the LVM partition created in Step 4 , then click Create
Container .
5c In the Create EVMS Container dialog box, select the partition, specify the container name
(such as
system
), then click Add Volume to create the
lvm/ system
container, where
system
is the container name.
5d Click OK .
The EVMS Configurator displays the
lvm/ system
container you just created, its size, and
free space.
