replication --resync --name <name> --role <source | target>

Description

Resynchronizes the replication process between a source and target container in a replication relationship on a QoreStor.

IMPORTANT: This command should only be used in an emergency situation with the help of Quest Support. Do not mistake this command as an ability to start a replication sync outside of the schedule window.

If your intention is to start a replication outside of the window, you can either delete the schedule, or add a temporary replication window to the current schedule and delete it when the systems are in sync.

Syntax

replication --resync --name <name> --role <source | target>

Where

--name   Name of container.
--role   Role of container.

Result

Successfully initiated replication resync on container dataStorage3.

replication --troubleshoot --peer <ip address | hostname>

Description

Troubleshoots the replication connections between a source and target container on a QoreStor.

NOTE: This command only reports 9915 and 9916 as succeeding against a replication peer that has Qorestor or DR Series replication configured to another system. If the peer is not currently using any replication ports, 9915 and 9916 will report as connection refused.

Syntax

replication --troubleshoot --peer <ip address | hostname>

Where

--peer   IP address or name of remote machine to troubleshoot.

Result

The following examples shows both successful and unsuccessful replication connection attempts:

Testing connection to port 9904... Connected!
Testing connection to port 9911... Connected!
Testing connection to port 9915... Connected!
Testing connection to port 9916... Connected!
Replication troubleshooting completed successfully - Connection to all ports is OK!
replication --troubleshoot --peer acme-205
Testing connection to port 9904... Connected!
Testing connection to port 9911... Connected!
Testing connection to port 9915...
Unable to connect to socket - Connection refused
Could not connect to acme-205 on port 9915 - (Connection refused)
Testing connection to port 9916...
Unable to connect to socket - Connection refused
Could not connect to acme-205 on port 9916 - (Connection refused)

<command> can be one of:
	--show           Displays command specific information.
	--add            Adds a replication link to a container.
	--update         Updates a replication link to a container.
	--delete         Deletes a replication link from a container.
	--start          Starts replication.
	--stop           Stops replication.
	--limit          Delete existing bandwidth rules for all ports and set new throttling limits.
	--resync         Initiates a replication re-sync.
	--troubleshoot   Troubleshoots replication connection.

Seed

The QoreStor seed operations allow for exporting data on the source to a portable seed device to then import the seed data to a primary target, and, if required, a secondary target as well. Replication seeding is an alternative to using network bandwidth for the initial re-synchronization of the source and target(s). After the target(s) are seeded, continuous replication can be started, which will keep the target(s) up to date by sending only unique data.

The QoreStor CLI seed commands support the following operations:

  • Create a job to perform seeding export or import.
  • Delete an existing seeding export or import job.
  • Specify containers for seeding export.
  • Remove a container which is already added for seeding export.
  • Add a device to be used for seeding.
  • Remove a device which is already added for seeding.
  • Start seeding process (export/import).
  • Stop running seeding process (export/import).
  • Start cleaner to process seed ZL logs on target.

NOTE: The seeding device must be a CIFS share: a USB device connected to a Windows or Linux system and shared for import as a CIFS-mounted folder.

NOTE: The following scenarios are not supported for seeding:

  • Import AND export from one share/device cannot occur at the same time.
  • Import from one share/device cannot be completed from multiple locations at the same time.
  • Export to a mount point can be completed only from one seed job. Multiple seed export jobs cannot send data to a single mount point.
