Increase the Size of /tmp and /opt File Systems

Default file system sizes are not always large enough for IBM image provisioning. If there is insufficient space in the /tmp or /opt file systems, agent deployment to NIM clients can fail. If the selected defaults are too small for the agents to install, increase them to at least 400 MB (for /tmp) and 700 MB (for /opt). If you do not have NIM scripts that increase the file system sizes, uncomment the chfs commands in the ca_post_install.sh script. chfs commands enable the NIM adapter to increase the file system size by using this script as a NIM script resource following NIM client imaging.

Note: Only enable these lines if your scripts do not already use them.

Follow these steps:

1. Change to the install_path/imaging/etc directory, and open the ca_post_install.sh script file.
2. Uncomment both chfs commands in the script by removing the leading # character.

   The commented line resembles the following example:

   #chfs -a size=$OPTFSSIZE /opt
   

   The uncommented line resembles the following example:

   chfs -a size=$OPTFSSIZE /opt
   

   Note: Optionally change the OPTFSSIZE and TMPFSSIZE variables to higher values than the default. Do not set them lower than the default.

3. Save the file and exit.
