Question

My Huawei FusionCompute environment uses Scale-out Block Storage. When I use Vinchin to back up Huawei FusionCompute VMs, the backup fails with the following message:

Backup VM failed.
Failed to calculate the size...

Answer

Issue Description

Huawei FusionCompute KVM For virtual machine backup/recovery of DSWare storage, please install the backup plug-in at the Hypervisor. Please download the backup plug-in from the login page, and deploy it on each host (physical server) that requires backup/recovery.


Resolution

1.Download the plugin

Log in to the Vinchin Backup & Recovery console and navigate to:

Resources > Infrastructure > Add

Select Huawei FusionCompute KVM, click Download Backup Plugin, and download the plugin package.

The package name may vary depending on the Vinchin version.

For example: vinchin-stack-patch-cloud-9.0.0.xxxxx-1.el7.x86_64.rpm

2.Install the plugin and configure the firewall.

Transfer the downloaded backup plugin package to each Huawei FusionCompute KVM hypervisor host that may run the protected VMs.

Note: The plugin package name varies depending on the Vinchin version. Use the actual file name downloaded from the Vinchin Backup & Recovery console.

For example: vinchin-stack-patch-cloud-9.0.0.xxxxx-1.el7.x86_64.rpm

 

Log in to the hypervisor host with root privileges, navigate to the directory where the plugin package is located, and install it:

Run: sudo rpm -ivh ./vinchin-stack-patch-cloud-*.rpm

 

After installation, verify that the plugin has been installed successfully:

Run: rpm -qa | grep vinchin-stack-patch-cloud

To allow communication required by the backup plugin, open TCP port 23100 on the hypervisor host firewall.

 

3. Create the FusionStorage mapping configuration file

An additional configuration file must be created on the Vinchin Backup Server to define the mapping between each FusionStorage management node and the hypervisor hosts that use the corresponding storage.

Step 1. Create the configuration directory

Run: sudo mkdir -p /etc/backup_system/fusion_compute_kvm

Step 2. Create the configuration file

Create the agent_ip.conf file under the directory created above:

Run: sudo touch /etc/backup_system/fusion_compute_kvm/agent_ip.conf

Open the file for editing:

Run: sudo vi /etc/backup_system/fusion_compute_kvm/agent_ip.conf

Step 3. Configure the storage-to-host mapping

Enter the FusionStorage management node IP address and the IP addresses of the hypervisor hosts that use the corresponding storage.

The format is:

<FusionStorage_Management_IP>=<Hypervisor_IP_1>,<Hypervisor_IP_2>,<Hypervisor_IP_3>

For example:

7.4.2.31=7.4.2.20,7.4.2.21,7.4.2.22
8.6.4.11=8.6.4.55

In this example:

  • 7.4.2.31 and 8.6.4.11 are FusionStorage management node IP addresses.
  • Hypervisor hosts 7.4.2.20, 7.4.2.21, and 7.4.2.22 use the storage managed by 7.4.2.31.
  • Hypervisor host 8.6.4.55 uses the storage managed by 8.6.4.11.

Important:

  • All configured IP addresses must be reachable from the Vinchin Backup Server.
  • If multiple hypervisor hosts use the same storage management node, separate the host IP addresses with English commas (,).
  • The FusionStorage management node IP can be checked in the FusionCompute interface under Resource Pool > Storage > Storage Resources.

Step 4. Verify the configuration

After saving the file,

run: cat /etc/backup_system/fusion_compute_kvm/agent_ip.conf

Verify that the storage management node and hypervisor host mappings are correct.

 

Then you can start the HuaweiFusionCompute VM Backup.
