Marostegui moved this task from Ready to In progress on the DBA board.

Going to deploy this on s6 on a couple of hosts in eqiad. If all goes well, I will try to deploy it entirely on codfw, so I can do eqiad once the dc switchover has happened.

s6 is fully done - only pending the master which will be done once eqiad is passive.

Marostegui moved this task from In progress to Blocked on the DBA board.

codfw is entirely done - waiting for the DC switch to finish everything in eqiad.
