Considerations
When an unexpected I/O failure occurs, the I/O Manager of OceanBase Database uses a probe thread to detect the status of the data disk. If the data disk status has not returned to the normal state after the timeout period specified by this parameter, the probe thread sets the data disk status to ERROR. This status triggers events such as node shutdown to prevent requests sent to the node from failing.
Examples
Set the maximum time that OceanBase Database waits for the data disk to return to the normal state after the data disk is set to ERROR to 300s.
