Description James Lamb 2008-01-23 14:48:05 UTC 
Description of problem:

I have created a kickstart configuration based on the Redhat Enterprise 5
installation manuals. In the partition section I have the following lines

clearpart --all
part /boot --fstype ext3 --size=300 --ondisk=sda
part swap --maxsize=8192 --recommended --ondisk=sda
part / --fstype ext3 --size=1 --grow --asprimary --ondisk=sda

When I do --recommended and --maxsize the swap size is never created as per the
documentation. (The minimum size of the automatically-generated swap partition
is no smaller than the amount of RAM in the system and no larger than twice the
amount of RAM in the system.). Unfortunately we currently have systems which
have greater than 32GB of memory and only 75GB hard drives. In this situation we
would like to have the local swap created as a maximum of 8GB that way we do not
use the entire local disk space. After we have provisioned the system we may
choose to put the servers on SAN etc and can allocate swap space accordingly.


Version-Release number of selected component (if applicable):
Redhat Enterprise Server 5

How reproducible:

Add the following lines into a kickstart configuration. 

clearpart --all
part /boot --fstype ext3 --size=300 --ondisk=sda
part swap --maxsize=8192 --recommended --ondisk=sda
part / --fstype ext3 --size=1 --grow --asprimary --ondisk=sda


Steps to Reproduce:

See Above.
  
Actual results:

The swap size appears to always be created as 2GB.

Expected results:

8GB swap size on a system with 32GB of ram.

The documentation states that "--maxsize" will only be taken into account when
"--grow" is present.
http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Installation_Guide-en-US/s1-kickstart2-options.html

This is still an issue with the recommendedSwap function in RHEL5.

Change the reccomendation formula

This patch changes the recommendation formula to be consistent with
documentation.
Comment 3 Martin Sivák 2008-06-12 12:54:20 UTC 
For the case you need (maximum 8GB of swap) you should probably use:

part swap --maxsize=8192 --grow --ondisk=sda
