Re: Upgrading mariadb-galera-server


Thanks Geoff, I never would have though of this without your mentioning it.

Unless I think there might be defects in my tables, do you think there's a
need to run mysql_upgrade for 10.0.15 -> .19?

Yes, you can do this. If you plan to run mysql_upgrade on each node
after upgrading, you may want to set wsrep_OSU_method to RSU before
doing so. I think this is especially important for this upgrade, since
mysql_upgrade in 10.0.19 calls REPAIR VIEW. That statement doesn't
exist in 10.0.15.




service mysql stop
yum update MariaDB-Galera-server MariaDB-client MariaDB-devel
MariaDB-shared galera-3
service mysql start
mysql --execute="SET GLOBAL wsrep_OSU_method=RSU;"
mysql --execute="SET GLOBAL wsrep_OSU_method=TOI;"
