You can manage the GooseFS client on the GooseFS cluster details page through the GooseFS console. For the concept of the GooseFS client, please see GooseFS Cluster Overview. The following is a detailed introduction on how to manage the clients of the GooseFS cluster.
2. In the left navigation, select GooseFS > Instance List to enter the GooseFS Cluster List Page.
3. Click the GooseFS cluster ID/name that needs to be managed to enter the cluster details page, then click Client Management in the sidebar to enter the Client Management subpage.
4. On the Client Management page, you can perform the following operations.
Add a client: Deploy the GooseFS client in a designated node. You can configure the following parameters. Once configured, click OK to proceed.
Node IP: The node where a new client needs to be added.
Mount Information:
Local Mounting Directory: The FUSE client's local mounting directory, used to access cached files on the GooseFS cluster, with a default value of /data/goosefs.
GooseFS Directory: GooseFS file system directory, i.e., the path in the GooseFS namespace, for example /0-aaa-int-1250000000/data. If unspecified, the default mount is the root path of the namespace, for example /0-aaa-int-1250000000.
Mount Parameters: FUSE client mount parameters. Default mount parameter allow_other means allowing other users to access; direct_io means enabling direct I/O. More parameters can be found in FUSE mount parameter list.
Batch Concurrency Level: Controls the number of tasks executed simultaneously (default is 1), suitable for batch mount clients.
Batch Failure Strategy: The strategy after task failure, which allows choosing to continue execution or terminate the execution of subsequent batches.
Update client: On the client management page, select the client that requires operation, click Update in the Action column, then click OK in the pop-up window. Used to enable service process keep-alive, automatically restart services when node exceptions occur, and automatically start clients when GooseFS cluster nodes restart abnormally, ensuring client availability.
Restart the client: On the client management page, select the client that requires operation, click Restart in the Action column, then click OK in the pop-up window. Used to restart the client after an exception, supporting modification of mount user, JVM parameters, and mount parameters.
Uninstall client: On the client management page, select the client that requires operation, click Uninstall in the Action column, then click OK in the pop-up window. Used to uninstall local file system mount points. After uninstallation, users can no longer access cached files on GooseFS via the client.
Note:
Uninstalling the client does not affect the existing cached files on GooseFS. However, if there are files being written to GooseFS when the client is uninstalled, it may cause file write failures.
Copy client: On the client management page, select the client that requires operation, click Copy in the Action column, then select the node IP for the new client to be created in the pop-up window and click OK. Copies the configuration information of the current client for creating a client on the new node.
