Overview
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. Notes:
Nodes in a GooseFS cluster must be in the same AZ and, whenever possible, in the same VPC to avoid high data request latency caused by cross-network traffic.
A GooseFS cluster includes three types of nodes: Master nodes, Worker nodes, and Client nodes. The roles of these nodes are as follows:
Master Node: The Master node is the primary control node of the cluster. At least one instance is required for deployment. In high availability mode, at least three instances are required for deployment.
Worker Node: Worker nodes are responsible for caching hot data. At least one instance is required as a Worker node. The number of Worker nodes can scale out linearly with the storage capacity that needs to be cached.
Client Node: Client nodes are used to read and write data in Worker nodes.
Operation Steps
2. In the left navigation, select GooseFS > Instance List to enter the GooseFS cluster list page.
3. Select the GooseFS cluster that you want to manage, go to the cluster details page, click Node Management in the sidebar, and enter the node management page.
4. On the node management page, click Add Node to add a node to the GooseFS cluster. The configuration items are described as follows:
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 formatted mounting is not enabled, there is no need to set the data disk mounting option during the creation flow; it can be mounted manually or using scripts. If formatted mounting is 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
5. After confirming that the above configuration information is correct, click OK to execute. The node creation process starts, and you can view the detailed progress of various node operations in the Task Center details.
6. After the node is created, to delete it, click Delete in the operation column.
Notes:
Before deleting a node, you must disable the GooseFS service on the node to avoid affecting 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. 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:
