sudo puppet agent -tv


Add the host back to the DSH list

The opposite of

Get the code review approved, +2 and then merge it in puppet. Either wait for the next puppet run or just force a puppet agent -tv on mw1228

Run scap pull on the host (was sync-common)

Background Wikimedia binaries#scap pull

ssh mw1228.eqiad.wmnet
scap pull

Final check before repooling

sudo service apache2 restart
curl -i http://localhost/

Add the host to conftool data

File a code review for conftool-data/nodes/eqiad.yaml adding the mw1228 host to api_appserver.

Review, +2 and the puppet-merge on Palladium. Wait for puppet to run.

Final metric check => mw1228

ssh mw1228.eqiad.wmnet
sudo tail -n 100 /var/log/apache2/other_vhosts_access.log | awk '{print $4" "$6}'  | sort | uniq -c | sort -n -k 1
