### Why is being done ###
For T88234 to be completed, https://dev.mysql.com/doc/refman/5.5/en/innodb-data-log-reconfiguration.html needs to be done. Since this also has other changes being bundled in, a small window of planned maintenance would be appropriate.
### What is going to be affected? ###
tools-db on labsdb1005. Would be down for a small amount of time.
### How is this being done? ###
https://dev.mysql.com/doc/refman/5.5/en/innodb-data-log-reconfiguration.html will be followed by hand.
### When is this planned? ###
<Not sure yet>
### What could go wrong? ###
Not sure. The world could end?
But realistically, I guess tools-db wouldn't come back up immediately, and would need a lengthy period of repair / troubleshooting before it comes back up. So loss of availability for it.
### Possible to roll back / stop mid way? Recovery plan if it goes belly up? ###
I guess we could just put the old config back, disable puppet, and start it back up? {{citationneeded}}
