Now that coal and coal-web have been moved to the webperf machines, a few cleanup steps are needed on both graphite1001 and graphite2001. These require root access (which I don't have), so leaving it to someone who does have that access to run them.

These can be run any time.

• Stop coal services. Coal should be already, just try again in case.

sudo systemctl stop uwsgi-coal
sudo systemctl stop coal

• Disable coal services

sudo systemctl disable uwsgi-coal
sudo systemctl disable coal

• Remove the systemd control files

sudo rm /lib/systemd/system/uwsgi-coal.service
sudo rm /lib/systemd/system/coal.service

• Reset the systemd daemon to remove those services

sudo systemctl daemon-reload

• Remove the symlinked coal whisper storage dir, create the new dir, and copy the data files
• note: leaves a copy of the files in /var/lib/coal, just in case.

sudo rm /var/lib/carbon/whisper/coal
sudo mkdir /var/lib/carbon/whisper/coal
sudo chown _graphite:_graphite /var/lib/carbon/whisper/coal
sudo cp -r /var/lib/coal/*.wsp /var/lib/carbon/whisper/coal/
sudo chown -R _graphite:_graphite /var/lib/carbon/whisper/coal/

• Remove nagios/nrpe configs:
• note: slightly adjusted reload command

sudo rm /etc/nagios/nrpe.d/check_uwsgi-coal.cfg
sudo systemctl reload nagios-nrpe-server.service

• Remove uwsgi config
• note: this was already done, it was "no such file or directory" already when i ran it

rm /etc/uwsgi/apps-enabled/coal.ini
rm /etc/uwsgi/apps-available/coal.ini

Give me a shout if there are any questions about this - marlier on IRC.
