How can I turn off my senhasegura instances for maintenance and turn them on again using an Arbiter?

F.A.Q

You must turn off the senhasegura instances in the reverse order of the cluster, in the example below we will use two instances.

1. Remove Arbitrator

2. Secondary Instance:

  • Run the following commands in sequence

orbit service mysql stop

orbit shutdown

3. Validate cluster status

orbit cluster status

4. Primary Instance:

orbit service mysql stop

orbit shutdown

To turn on, the procedure must be the opposite of the one mentioned above, it must be following the order of the cluster.

1. Primary Instance:

  • Turn on the instance and run the following command:

orbit cluster start

Wait 5 minutes for correct database initialization.

2. Secondary Instance:

  • Turn on the instance, wait 5 minutes for automatic synchronization and validate that the secondary is accessible. Otherwise, run the following command:

orbit cluster start

3. Validate cluster status

orbit cluster status

4. To add the Arbiter to the cluster, follow the documentation starting from step 6.
