About this task

This task tracks the progress of the replication.

Prerequisites

A replica definition.

Instructions

Query for the replicating volumes on both source and target in order to see the progress of the replication. See the following examples for the way this query is used, and the data that can be queried for.

Querying for the replica from InfiniShell

The replica.query command displays the status of the replication. In the following example, the sync job has ended, so the State of the replication is IDLE and the Progress of the replication is 100%.

LOCAL DATASET TYPE  ROLE    REMOTE SYSTEM  REMOTE DATASET STATE        PROGRESS  THROUGHPUT  RPO STATE  RESTORE POINT
cg-1  CG            SOURCE  ibox3000       ibox1140_cg-1  IDLE         100%               -  OK         2015-09-06 11:05:04
cg-2  CG            SOURCE  ibox3000       ibox1140_cg-2  REPLICATING  1%                 -  LAGGING    2015-09-06 07:24:34

Whenever the replication was queries amidst the sync job, the State is INITIAL_REPLICATION and the Progress is a number between 0% and 100%.

(Some fields were removed from this example, in order to allow for a clear display on this document.)

LOCAL DATASET TYPE  ROLE    REMOTE SYSTEM  REMOTE DATASET STATE                       PROGRESS  THROUGHPUT  RPO STATE  RESTORE POINT
cg-3  CG            SOURCE  ibox3000       ibox1140_cg-1  INITIAL_REPLICATION         10%                -          -              -

Available fields

You can set the query to display the following fields (some of them are not included in the default output that is shown above).

To select which fields to display, run replica.query with the columns operator. Available columns are:

local_pool_name	The name of the pool that the local dataset belongs to.
remote_system	The name of the remote system.
state_description	A plain English description of the state of the replication.
updated_at	The last time the replication was updated. Usually, this is the timestamp of the last sync job.
created_at	The time the replica was created.
progress	The completion of a currently running sync job, in percents.
restore_point	The time of the last replicated snapshot on the source, that is known for sure to be replicated to the target. This is valid only on the source.
state_reason	A sub code of the replica state.
last_synchronized	The last time data was replicated from the source to the target.
remote_dataset	The name of the dataset on the remote system.
role	The role of the local dataset. Either Source or Target.
sync_duration	The duration of the last sync job.
local_dataset	The name of the dataset on the local system.
remote_pool_name	The name of the pool that the remote dataset belongs to.
state	The state of the replication. Available values: Unknown Idle Replicating
sync_interval	The preset interval between sync jobs.
staging_area_size	The capacity that is dedicated for replica snapshots. This field is available only on the target system.

For more information on how to select which columns to display, see: Controlling the columns of the displayed query output.

Tracking the replication from the GUI

The Replication screen displays the state of each replica.
