Red Hat Bugzilla – Bug 429858
part swap --recommended --maxsize=8192 does not work
Last modified: 2008-06-12 10:07:30 EDT
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. Additional info:
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.
Created attachment 309065 [details] Change the reccomendation formula This patch changes the recommendation formula to be consistent with documentation.
For the case you need (maximum 8GB of swap) you should probably use: part swap --maxsize=8192 --grow --ondisk=sda
