VOLUME_ALARM_CGS_VIOLATING_RACK_RELIABILITY

Meaning

A volume has violated rack reliability constraints. This alarm is raised after more parity containers of a CG are allocated and located in a rack of the volume ectopology. This might occur when nodes in the backend EC volume are moved across racks of ectopology.

Resolution

CGs are properly moved to another rack. The software triggers internal actions that move CG containers across racks to ensure that they conform to honorrackreliability requirements. After required containers are moved, the software clears the alarm.

Configuration
Configurable in volume properties. See the honorrackreliability ec rack reliability parameter in Volume Modify or volume create for more information.
