Ich habe MariaDB Cluster zuvor bereitgestellt, und dieses Problem tritt erst kürzlich (ich habe dieses Problem nicht zuvor und ich weiß nicht warum).MariaDB Galera Cluster wird nicht synchronisiert
Ich habe Server 1, 2 und 3. Ich habe einen INSERT-Befehl auf Server 3 ausgeführt, die Tabellen auf Server 1 und 2 bleiben jedoch unverändert.
3 Server sind in verschiedenen Teilen der Welt. After the INSERT command, the state uuid remains the same. Hier
ist der Status des Servers 1:

iptables auf allen drei Servern sind so eingestellt, dass alle Eingabe- und Ausgabe-Datenverkehr akzeptiert werden.
Das Protokoll zeigt, dass alle Server mit dem Cluster verbunden und synchronisiert wurden.
Weiß jemand warum? Vielen Dank.
Da die MyISAM-Speicher-Engine nicht transaktional ist, wird sie in Galera nicht unterstützt. FWIW, Änderungen in MySQL-Tabellen können immer noch auf andere Knoten repliziert werden, indem Sie wsrep_replicate_myisam aktivieren. Aber diese Funktion ist experimentell. –
erwägen, Kunden zu zwingen, InnoDB-Engine zu verwenden. Siehe https://mariadb.com/kb/en/library/server-system-variables/#enforce_storage_engine 'SET GLOBAL enforce_storage_engine = InnoDB;' –
