move chunk

Moves a listed set of chunks from one shard to another shard or multiple shards.

Syntax

move chunk -chunk {chunk_id_list | ALL}
           -source shard_name
          [-target shard_name]
          [-timeout]
          [-verbose]
          [-copy]

Options

Table 2-66 GDSCTL move chunk Options

Option	Description
-chunk {chunk_id_list | ALL}	Specify a comma-separated list of chunk IDs. If -chunk ALL is specified without the -target option, all of the chunks are removed from the source shard and distributed to all of the remaining shards in a round-robin manner.
-copy	Copy the chunk instead of moving (OGG only).
-source shard_name	Specify the name of the source shard.
-target shard_name	Specify the name of the target shard.
-timeout	Specify a connection retention time-out for the interval between when FAN is sent to the clients and a chunk going into read-only mode or down.
-verbose	Enable verbose output mode.

Usage Notes

Chunks cannot be moved between shards that belong to different shardgroups.

If -chunk ALL is specified without the -target option, all of the chunks are removed from the source shard and distributed to all of the remaining shards in a round-robin manner.

Examples

Move chunks 3 and 4 from SALE1 to SALE3.

GDSCTL> move chunk -chunk 3,4 –source sale1 –target sale3  

Move all chunks from sale1 and distribute evenly among the remaining shards.

GDSCTL> move chunk -chunk ALL -source sale1
