Problem with Master/Slave <=> Master/Slave <=> Master/Slave Replication
I am having a Problem with getting mariadb works flawless using a
Master/Slave <=> Master/Slave <=> Master/Slave
The First Time i was able to insert a row on the Master Server
and the data was reproduced/replicated to all servers.
At this Time i thinked everything is fine now.
But then when i tryed to deleted the new Created Row on Master
the Data was only deleted on the Master Server while
the others Servers  and  still had the data!
I expected that the deleted row should be also deleted on all
master/slave servers but it did not!
How can i solve this Problem? And what is actually the Problem with
MySQL/MariaDB? I am getting the impression that MariaDB is really bad
when it comes to Replication/Sync of Data in a Distributed Architecture.
As a Example let say on server has to reboot because of a Cloud
maintenance. From what i see this MaraiDB server will be forever
corrupted after the restart and never sync again as first it has to
manually be adjusted to the master bin log position and second it has
also be told to work as a slave after this.
Not really what i would expect from a autonomous replicating Master
Slave Data Base Server after a restart!
Hope somebody can tell me how to resolve all this Sync Problems so
finally MariaDB Master/Slave Database Server work flawless without to
worry that sooner or later a node or a few of them will get useless and
Thanks in advance for any helpful Tip and Answer!
