Chapter 5. Troubleshooting
This chapter provides tips for determining the cause of and resolving the most common errors
associated with Red Hat Satellite. If you need additional help, contact Red Hat Network support at
https://access.redhat.com/support/. Log in using your Satellite-entitled account to see the full list of
options.
To begin troubleshooting general problems, examine the log file or files related to the component
exhibiting failures. A useful exercise is to issue the tail -f command for all log files and then run yum
list. You should then examine all new log entries for potential clues.
5.1. Disk Space
My disk space filled up fast . What happened and what should I do?
A common issue is full disk space. An almost sure sign of this is the appearance of halted writing
in the log files. If logging stopped during a write, such as mid-word, the hard disks may be full. T o
confirm this, run this command and check the percentages in the Use% column:
# df -h
In addition to log files, you can obtain valuable information by retrieving the status of your Red Hat
Satellite and its various components. T his can be done with the command:
# /usr/sbin/rhn-satellite status
In addition, you can obtain the status of components such as the Apache Web server and the Red
Hat Network T ask Engine individually. For instance, to view the status of the Apache Web
server, run the command:
# service httpd status
5.2. Installing and Updating
SELinux keeps giving me messages when I'm t rying to install. Why?
If you encounter any issues with SELinux messages (such as AVC denial messages) while
installing Red Hat Satellite, be sure to have the audit.log files available so that Red Hat Support
personnel can assist you. You can find the file in /var/log/audit/audit.log and can attach
the file to your Support ticket for engineers to assist you.
I changed /var/satellite to an NFS mount, and now SELinux is stopping it from
working properly. What do I need to do?
SELinux parameters need to be changed based on the new NFS mount in order for SELinux to
allow that traffic. Do this with the command:
# /usr/sbin/setsebool -P spacewalk_nfs_mountpoint on
If you are using Red Hat Enterprise Linux 6, you will also need to run the command:
# /usr/sbin/setsebool -P cobbler_use_nfs on
