Possible? upgrading gallera cluster without service interruption
We would like to upgrade from 5.5.33a+maria-1~saucy to 5.5.39+maria-1~saucy on
a running cluster without service interruption.
So we took down one node, upgraded and restarted that instance...
It fails to connect to the next gcomm server. MariaDB fails to start.
We tested network connectivity, there is no issue we could detect.
We downgraded back to 5.5.33a+maria-1~saucy and the connectivity issue
So my question here is: Is it possible to upgrade the cluster without
interruption, or do we have to shut the whole cluster down, upgrade every node
and then restart everything?
