S01012

Error Code

S01012

Error Message

No available replica for the chunk <chunkId> is found on the controller. RefId:S01012

Probable Causes

A transaction checks the number of available replicas after acquiring distributed locks for the involved chunks. This error is reported if the number is 0, and the transaction is rolled back.

Specific reasons include:

All nodes hosting the chunk replicas are offline.
The online replicas of the chunk have versions inconsistent with the controller.

Solutions

Execute getClusterChunksStatus on the controller to view the status of each chunk replica for further troubleshooting.
