I have a 3 node test cluster that I’m trying to upgrade to 5.6.
Unfortunately, I can’t even get the nodes to stop gracefully so I can upgrade them.
‘/etc/init.d/mysql stop’ returns “fail” after 5 minutes.
‘service mysql stop’ just seems to call /etc/init.d/mysql stop
‘mysqladmin shutdown’ returns immediately without any message
‘kill -TERM’ doesn’t work
The only thing that works is kill -9 which doesn’t leave things in a good state for an upgrade.
This cluster has practically no load at all, maybe 1-5 queries per second.
It doesn’t appear to be a problem with innodb either:
I’m using the latest packages for Ubuntu trusty.
