MapR 5.0 Documentation : dump rereplicationinfo

The maprcli dump rereplicationinfo command enables you to view information about the re-replication of containers. For best results, use the -json option when running dump rereplicationinfo from the command line.

Re-replication occurs whenever the number of available replica containers drops below the number prescribed by that volume's replication factor. Re-replication may occur for a variety of reasons including replica container corruption, node unavailability, hard disk failure, or an increase in replication factor.

Syntax

CLI
maprcli dump rereplicationinfo
    [-cluster <cluster name>]
RESTN/A

Parameters

Parameter

Description

-cluster <cluster name>

The cluster on which to run the command. If this parameter is omitted, the command is run on the same cluster where it is issued. In multi-cluster contexts, you can use this parameter to specify a different cluster on which to run the command.

Output

The maprcli dump rereplicationinfo command returns information about the ongoing re-replication of replica containers including the destination IP address and port number, the ID number of the destination file server, and the ID number of the destination storage pool.
