Hi Niklaas,

in MariaDB 10.1, Galera replicator needs to be explicitely enabled. Try adding this to your configuration file:

wsrep_on=ON

Kind regards

Hello,

I'm trying to setup a galera cluster on FreeBSD. I followed the
instructions on [1] but every time I issue

    SHOW STATUS LIKE 'wsrep_cluster_size';

I get

    +--------------------+-------+
    | Variable_name      | Value |
    +--------------------+-------+
    | wsrep_cluster_size | 0     |
    +--------------------+-------+
    1 row in set (0.00 sec)

So, the cluster is not working. This is the configuration of the node
that I want to set as primary:

-----------------------------------8<-----------------------------------

[mysqld]
datadir=/var/db/mysql
socket=/tmp/mysql.sock
user=mysql
binlog_format=ROW
bind-address=0.0.0.0
default_storage_engine=innodb
innodb_autoinc_lock_mode=2
innodb_flush_log_at_trx_commit=0
innodb_buffer_pool_size=122M
wsrep_provider=/usr/local/lib/libgalera_smm.so
wsrep_provider_options="gcache.size=300M; gcache.page_size=300M"
wsrep_cluster_name="klaas_cluster"
wsrep_cluster_address="gcomm://"
#wsrep_cluster_address="gcomm://10.1.7.1,10.1.7.2,10.3.7.1"
wsrep_sst_method=rsync

[mysql]
wsrep_cluster_name=klaas_cluster
wsrep_cluster_address="gcomm://10.1.7.1,10.1.7.2,10.3.7.1"
wsrep_node_name=box-hlm-01
wsrep_node_address="10.1.7.1"

[mysql_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

----------------------------------->8-----------------------------------

On the other two nodes the configuration is the same, except (1) only
the second `wsrep_cluster_address` exists; (2) `wsrep_node_address`
differs, obviously.

Instead of using an "empty" `wsrep_cluster_address` I also tried setting

    mysql_args="--wsrep-new-cluster"

in /etc/rc.conf without getting the desired result. The logs lack any
relevant warnings or errors:

Any help is very much appreciated.
