RHEL 7 Teaming tip.

Share this link

When preparing an exam like the RHCSA or the RHCE exams, it is relatively difficult to remember the commands with all their options, the configuration procedures with all their details, and finally the mistakes to avoid. This is even worse if you have little or no real experience. In this case, you have to make up for your lack of experience by being clever.

One of the main tips is to know how to find the relevant information in the current system itself through man pages, default configuration files with theirs comments (Apache, Samba, etc), and configuration examples coming with some packages (Postfix, MariaDB, etc).

Recently one reader, Carlos G Mendioroz, left a very good comment about teaming configuration. If you don’t remember some details, several configurations are available in the /usr/share/doc/teamd-*/example_configs directory.

For example, to get an example of a round robin configuration, type:

# more /usr/share/doc/teamd-1.9/example_configs/roundrobin.conf
{
"device": "team0",
"runner": {"name": "roundrobin"},
"ports": {"eth1": {}, "eth2": {}}
}

It is clear that this doesn’t explain everything nor replace practice. If you spend your time searching for man pages information or searching for example configuration, time will run out and you won’t be able to complete the different tasks in time.
