Node Replacement

{{ $t('productDocDetail.updateTime') }}: 2026-01-05

Description

When a node in the cluster goes offline due to a physical failure, it needs to be replaced with a new node.

Precautions

  1. Node replacement will trigger data rebuilding, which will occupy IO. It is recommended to consult with customers and operate during non-production hours.
  2. It is required that the CPU frequency, memory size and frequency, and hard disk capacity of the new node should not be lower than those of the original faulty node.
  3. If the number of hard disks of the new node is larger than that of the original faulty node, the capacity must be expanded after the node is replaced.
  4. It is recommended that the capacity of a single disk of the new node be the same as that of the original failed node.
  5. The new node's management IP address cannot be the same as the original faulty node.

Prerequisites

  1. The IP addresses of each network plane of the new node have been planned.
  2. The aSV software has been installed on the new node and is consistent with the original version (including patches), and the management IP has been set.
  3. The management interface, VXLAN port, overlay network interface, and storage port of the new node have been correctly connected to the network.

Steps

  1. Find the faulty node in Nodes and click Replace Host.
  1. Confirm that the configuration of the new node is not lower than the original faulty node, and after installing the aSV software correctly, check the I am ready checkbox and click Next.
  2. Select the newly discovered node, click Next, and replace the node after adding it to the cluster.
  3. Configure the network, select the storage communication port, and configure the communication network port IP.
  4. Confirm the configuration: choose whether to refer to the disk configuration mode of the old host, check I am sure I want to replace the physical host, and click Finish.
  5. When the detection is passed, click Confirm, you can see the progress of the host replacement in the task center and wait for the host replacement to complete.
  6. After the data rebuilding is completed, perform a Health check to confirm that the platform is running.
