copyReplicas
Syntax
copyReplicas(srcNode, destNode, chunkId)
Arguments
srcNode is a string indicating the alias of origination node.
destNode is a string indicating the alias of destination node.
chunkId is a string or a string vector indicating ID of chunks.
Details
Copy replicas of one or multiple chunks from a node to another node. If the destination node already has the chunk, the command is skipped.
This command can only be executed by an administrator on a controller node.
We can check the execution status with function getRecoveryTaskStatus .
Examples
Copy replicas of all chunks on “node1” to “node2”.
$ chunkIds=exec chunkId from pnodeRun(getAllChunks) where node="node1"
$ copyReplicas("node1","node2",chunkIds);
