You can manage GooseFS cluster nodes through the GooseFS console on the cluster details page. For the concept of GooseFS cluster nodes, please see GooseFS cluster overview. The following is a detailed introduction on how to manage GooseFS cluster nodes.
Note:
Nodes in the GooseFS cluster must be in the same availability zone and preferably in the same VPC to avoid extended request delay caused by traffic routing.
The GooseFS cluster includes three main categories of nodes: Master node, Worker node, and Client node. The role of different nodes is as follows:
Master nodes: The master node is the cluster master node, requiring at least one instance deployment. In high availability mode, a minimum of three instance deployments is required.
Worker node: The worker node is responsible for caching hot data and requires at least 1 instance as a worker node. The number of worker nodes can linearly scale-out as needed based on the storage capacity to be cached.
Client node: The Client node is used for read-write access to data in the Worker node.
2. In the left navigation, select GooseFS > Instance List to enter the GooseFS cluster list page.
3. Select the GooseFS cluster to manage, enter the cluster details page, click Node Management in the sidebar to open the node management subpage.
4. On the node management page, you can perform the following operations.
Add Node: Used to add a node to the GooseFS cluster. The following are the optional parameters:
Instance Type: Currently only support adding CVM instances.
Node Type: Supports Worker nodes and Client nodes. Fully managed mode only supports Client nodes.
Node IP: Add node.
Associated Configuration Group: The configuration group that the node must be associated with.
Formatted Mounting: Used to format the disk and perform file system mounting. Users can choose whether to perform formatted mounting. If not enabled, there is no need to set the data disk mounting option during the creation process; it can be mounted manually or using scripts. If enabled, the device name, system formatting, mount point, and other parameters need to be filled in.
Device Name: The hardware device that needs to be mounted, usually a specific disk partition. It requires logging in to the machine to view and is generally located in the /dev path.
Format System: Linux file system type.
Mount Point: File system mount point
Delete Node: Used to delete a designated node in a GooseFS cluster.
Note:
Disable the GooseFS service on the node before deleting it to avoid impacting the business.
Deleting the last Master node in a cluster is equivalent to deleting the cluster. If you need to delete, refer to Deleting a GooseFS Cluster.
5. Enter the required parameters for various operations as needed, confirm and click Confirm to execute.
6. Enter the node management process. You can view detailed progress of various node operations in the Task Center details.
Following Steps
After creating nodes in the GooseFS cluster, you can add namespaces, manage node configurations, and install clients on nodes according to business needs. For details, see the following document:
