Description
This test case helps you generate and upload boot speed data when booting with your usual set of services.
How to test
- Ensure Bootchart is installed according to these instructions
- Ensure you have reported your system information to Smolt according to these instructions
- Ensure the readahead package is installed, with yum or the graphical package manager
- Edit the file /etc/sysconfig/readahead and change READAHEAD="yes" to READAHEAD="no" if it is currently set to yes
- Reboot the system
- Log in, then run this command (from your home directory, or from a specially created directory if you want to keep things tidy):
# cp /var/log/bootchart.tgz ./Bootchart-`head -n1 /etc/sysconfig/hw-uuid`-myservices.tgz
- Edit the file /etc/sysconfig/readahead and change READAHEAD="no" to READAHEAD="yes" if it is currently set to no
- Type:
# touch /.readahead_collect
- Reboot, then as soon as the system is fully booted, reboot again
- Log in, then run this command (from your home directory, or from a specially created directory if you want to keep things tidy):
cp /var/log/bootchart.tgz ./Bootchart-`head -n1 /etc/sysconfig/hw-uuid`-myservices-ra.tgz
- Optionally, you can run the command bootchart as root to generate a bootchart image, then save that with a similar, unique filename
Expected Results
- Two different sets of boot speed data should be generated and saved with unique file names.
