ReleaseEngineering/How To/Shut off all updates

On occasion we need to shut off all updates for all products/branches. This could happen because of a disastrous update scenario, a downtime, or some other unforeseen reason.

Currently our updates are split across two different systems (AUS3 and Balrog), so we need to make changes to both of those systems to do this:

Shutting off updates in AUS3

• Log on to aus3-staging via ssh (you should be able to log in with your own LDAP account)
• Run the following:

sudo su -
chmod 700 /opt/aus2/incoming

Re-enabling

Run the following:

chmod 755 /opt/aus2/incoming

Shutting off updates in Balrog

• Go to the Balrog Admin interface's rules page.
• Add a new rule with the following properties:
  • Mapping: No-Update
  • Background Rate: 100
  • Priority: 100

Re-enabling

• Go to the Balrog Admin interface's rules page.
• Find the rule added in the previous section (be careful, as there are other No-Update rules that are in place for OS blocking. You want the one that doesn't specify _anything_ other than Mapping, Background Rate, and Priority).
• Change its "Priority" to 0 and click its "Update" button.
