Group Replication is a new technology and from time to time we encounter issues.
Today my issue is the primary node server crash and it comes up again it didn’t join my cluster.

MySQL Group Replication is a MySQL Server plugin that enables you to create elastic, highly-available, fault-tolerant replication topologies.
Groups can operate in a single-primary mode with automatic primary election, where only one server accepts updates at a time. Alternatively, for more advanced users, groups can be deployed in multi-primary mode, where all servers can accept updates, even if they are issued concurrently.
There is a built-in group membership service that keeps the view of the group consistent and available for all servers at any given point in time. Servers can leave and join the group and the view is updated accordingly. Sometimes servers can leave the group unexpectedly, in which case the failure detection mechanism detects this and notifies the group that the view has changed. This is all automatic.
As i prepare to roll out a 6 Node Group Replication in production, we are currently in the process of setting up our UAT environment.
It will be running 3 Node cluster.
On my previous post I intalled and configure a 3 node MariaDB 10.1 cluster for my evaluation purpose
for our current project…
Let install the latest MaxScale .. —>
Currently i’m on the process of choosing the matured product like galera clustering vs the new MySQL Group Replication.
I’m my past engagement, i only work on MariaDB 5.5 and 5.6 with galera cluster running on cloud.
The following are the step to create my test machine. —>
Currently been busy with doing some migration stuff from MySQL to NuoDB.
Since my binlog directory is almost full, decided to delete its content.
no issue on my database while its running but when i restarted my database got below error. —>
I’d been a little bit busy working MariaDB lately… deploying database in cloud since our company is gearing towards open source.
We’d been using MariaDB 5.5 for a while now and need to upgrade to #MariaDB 10 Continue reading
