Continuent is pleased to announce that Tungsten Clustering 6.0.2 and Tungsten Replicator 6.0.2 are now available!
Our 6.0.2 release is a critical bug fix for the cluster Manager logic within a Multimaster cluster.
All current users of v6.0.0 and v6.0.1 should upgrade IMMEDIATELY!
Fixes issue CT-672: the manager could set the master to read-only when performing a switch operation.
There is a procedural work-around if you get into this situation:
shell> cctrl
cctrl> use {dataservice where the master was switched or failed over to}
cctrl> set policy automatic
cctrl> datasource {new-master} offline
The Manager rules in automatic mode will put the datasource back online and, in the process, will clear the mysql read-only flag.
The alternative, if the cluster is in maintenance mode:
shell> cctrl
cctrl> datasource {new-master} offline
cctrl> datasource {new-master} online
