Globus Connect Server Node Update
The globus-connect-server node update command updates information about a Data Transfer Node configured to run services for an endpoint. Its primary use is to disable or re-enable a node when doing system maintenance. It can change the IP address associated with the node. After disabling a node, the endpoint may have intermittent errors for up to two minutes while DNS changes propagate.
In order to use this command, one of your Globus identities must have an
administrator role on the endpoint.
To disable a node, use the command-line option --disable. This will have the following effects:
The node’s IP address is removed from the DNS entry used by the Globus Services. This may take a few minutes to propagate.
Future requests for management or data transfer service that are sent to the disabled node are rejected with a
503 Service Unavailableerror. You can also use
systemctl stop gcs_managerand
systemctl stop gcs_manager_assistantto stop the Globus services entirely.
--disableoption to disable all nodes for an endpoint, you will no longer be able to access the endpoint for any management or data access tasks. To fix this problem, use the globus-connect-server node setup command on any of the nodes. This will reset the node’s status to
activeand restart the services on that node.
To re-enable a node, use the command-line option --enable. This will update the node’s status to active and add it back to the DNS entry for the endpoint.
You can also use this command to change the IP address associated with a node, for example, if you are changing the network configuration of the node. To do so, pass the --ip-address IP-ADDRESS parameter on the command-line.
