Switching CDP task mode

CDP tasks can be switched between tracking-only mode and normal mode.

In tracking-only mode, only dirty extents are recorded and no data replication is performed.
In normal mode, data replication proceeds.

Switching to tracking-only mode

Procedure

Switch by the task ID:

zbs-cdp job enter_tracking_only <id> [options]

Switching by the local volume ID:

zbs-cdp job enter_tracking_only_by_volume <volume_id> [options]

Parameter description

Parameter	Description
`id`	The task ID.
`volume_id`	The local volume ID.
`--sync` / `--no-sync`	Optional. Specifies whether to wait synchronously until the task is switched. Default: `True`.
`-v` / `--version <VER>`	Optional. Specifies the CDP protocol version (`v1` or `v2`).

Output example

zbs-cdp job enter_tracking_only c0bb7d91-e74b-434c-98e2-00c57e8bb93f

Output note

If the command succeeds, no output is displayed.

Procedure

Run the following command on any node in the cluster:

zbs-cdp job enter_tracking_only_by_group <group> [options]

Parameter description

Parameter	Description
`group`	The CDP task group name.
`--sync` / `--no-sync`	Optional. Specifies whether to wait synchronously until the task group is switched. Default: `True`.
`-v` / `--version <VER>`	Optional. Specifies the CDP protocol version (`v1` or `v2`).

Output example

zbs-cdp job enter_tracking_only c0bb7d91-e74b-434c-98e2-00c57e8bb93f

Output note

If the command succeeds, no output is displayed.

Exiting tracking-only mode switches the tasks back to normal mode, and normal data replication resumes.

Procedure

Exit by the task ID:

zbs-cdp job exit_tracking_only <id> [options]

Exiting by the local volume ID:

zbs-cdp job exit_tracking_only_by_volume <volume_id> [options]

Parameter description

Parameter	Description
`id`	The task ID.
`volume_id`	The local volume ID.
`--sync` / `--no-sync`	Optional. Specifies whether to wait synchronously until the mode is exited. Default: `True`.
`-v` / `--version <VER>`	Optional. Specifies the CDP protocol version (`v1` or `v2`).

Output example

zbs-cdp job exit_tracking_only c0bb7d91-e74b-434c-98e2-00c57e8bb93f

Output note

If the command succeeds, no output is displayed.

Batch exiting tracking-only mode switches all CDP tasks in the specified CDP task group from tracking-only mode to normal mode.

Procedure

Run the following command on any node in the cluster:

zbs-cdp job exit_tracking_only_by_group <group> [options]

Parameter description

Parameter	Description
`group`	The CDP task group name.
`--sync` / `--no-sync`	Optional. Specifies whether to wait synchronously until the mode is exited. Default: `True`.
`-v` / `--version <VER>`	Optional. Specifies the CDP protocol version (`v1` or `v2`).

Output example

zbs-cdp job exit_tracking_only c0bb7d91-e74b-434c-98e2-00c57e8bb93f

Output note

If the command succeeds, no output is displayed.
