How to do a Rolling Restart of Your MySQL Cluster This page last changed on Apr 03, 2009 by stephanielewellen. How to do a Rolling Restart of Your MySQL Cluster Be sure to comply with the MySQL Cluster rules regarding reconfiguration as published here: Performing Rolling Restart of MySQL Cluster. Steps 1. Stop the vdadb:core service on the Primary host. Execute svcadm disable vda:/application/database/vdadb:core. Verify that it has been stopped by executing svcs svc:/application/database/vdadb:core (this can take a couple of minutes). You should see an output similar to this one: STATE disabled STIME FMRI Dez_09 svc:/application/database/vdadb:core 2. Start the vdadb:core service again on the Primary host. Execute svcadm enable svc:/application/database/vdadb:core. This makes the new MySQL Cluster configuration effective. Verify that the service has been started by executing svcs svc:/application/ database/vdadb:core (again, this may take a couple of minutes). You should see an output similar to this one: STATE online STIME FMRI Dez_09 svc:/application/database/vdadb:core 3. Stop your first data node. Execute svcadm disable svc:/application/database/vdadb:core on your first Secondary host. Verify that is has been stopped by executing svcs svc:/application/database/vdadb:core (this can take a couple of minutes). STATE disabled STIME FMRI Dez_09 svc:/application/database/vdadb:core 4. Once the data node has been stopped, start it again. Execute svcadm enable svc:/application/database/vdadb:core and wait until it has been started (again, this might take a couple of minutes). Verify that the service has been started by executing svcs svc:/ application/database/vdadb:core. You should see output similar to this one: STATE online STIME FMRI Dez_09 svc:/application/database/vdadb:core 5. Repeat the last two steps on your second Secondary host. 6. Stop the SQL node on every secondary host. Execute svcadm disable svc:/application/database/vdadb:sql. Verify that is has been stopped by executing svcs svc:/application/database/vdadb:sql (this can take a couple of minutes).
