I'm using 10.1.16-MariaDB-1~xenial from the official MariaDB apt repository for 10.1 [stable], via the University of Texas mirror.

I had a perfectly functioning MariaDB Galera cluster setup on 3 Ubuntu 16.04 servers.

Then I upgraded them. Now I have nothing.

The upgrade to 10.1.16 failed, and quickly brought down the whole cluster. I don't have the output, but dpkg failed on setting up mariadb-server and mariadb-server-10.1.

I have backups, so I purged all traces of MariaDB/MySQL/Galera from my servers (including removing /var/lib/mysql/, /etc/mysql/, and /var/log/mysql/) and started over. However, now, with a clean install on each server, none of the standard system startup scripts work. I suspect this is why the upgrade process through apt failed, too.

I've tried each of the following on my first node:

service mysql bootstrap
service mysql bootstrap --wsrep-new-cluster
service mysql bootstrap --wsrep-cluster-address="gcomm://"
service mysql start
service mysql start --wsrep-new-cluster
service mysql start --wsrep-cluster-address="gcomm://"
systemctl start mariadb
systemctl start mariadb --wsrep-new-cluster
systemctl start mariadb --wsrep-cluster-address="gcomm://"

Every single one gives me the same output:

Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xe" for details.

systemctl status mariadb.service:

The only way I can start my servers now is by manually executing:

sudo -u mysql mysqld --wsrep-cluster-address='gcomm://'

On the first node, and then:

sudo -u mysql mysqld --wsrep-cluster-address='gcomm://ip1,ip2,ip3'

On the other two nodes. That works, and I have a working cluster again. But now, systemd/systemctl have no idea the service is running. It seems like the systemd startup scripts can't use the wsrep-cluster-address setting in my configuration files at all. Specifying it to service or systemctl command line does not work either.

How am I supposed to start mariadb?

There was a bug in galera_recovery.sh script. https://jira.mariadb.org/browse/MDEV-10396

  • Patching /usr/bin/galera_recovery per the bug comments fixed my issue on each one of the cluster servers that I upgraded to 10.1.16, hopefully this will make it into a release coming soon. and this comment will help someone else.

I've been able to temporarily alleviate my problems by downgrading to 10.1.14:

Now, I can start my first node with galera_new_cluster and all other nodes with service mysql start.

There must be a bug with the systemd/systemctl scripts in 10.1.16.
