4.17.4. Recommended Partitioning Scheme
Unless you have a reason for doing otherwise, we recommend that you create the following partitions
for
Itanuim
systems:
•
A
/boot/efi/
partition (100 MB minimum) — the partition mounted on
/boot/efi/
contains
all the installed kernels, the initrd images, and ELILO configuration files.
Warning
You must create a
/boot/efi/
partition of type VFAT and at least 100 MB in size as the first
primary partition.
•
A swap partition (512 MB minimum) — 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 (but no larger than 2 GB). It must be of type swap.
Tip
If your partitioning scheme requires a swap partition that is larger than 2 GB, you should create
an additional swap partition. For example, if you have 4 GB of RAM, you may want to create two 2
GB swap partitions.
•
A
root
partition (900 MB - 5.0 GB) — this is where "
/
" (the root directory) is located. In this
setup, all files (except those stored in
/boot/efi/
) are on the root partition. It must be of type
ext3 or ext2.
•
A
/var/
partition (3.0 GB or larger) — the
/var/
partition is where variable data files are writ-
ten. This includes spool directories and files, administrative and logging data, and transient and
temporary files. Updates that are applied to Red Hat Enterprise Linux are written to the
/var/
partition.
Unless you have a reason for doing otherwise, we recommend that you create the following partitions
for x86, AMD64, and Intel® EM64T systems
:
•
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, but no more than 2048 MB (or 2 GB). It must be of type 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
