How do I back up the CLM deployer host?

Purpose

Perform the following steps to back up the CLM deployer host in a CLM cluster. A CLM deployer host backup is crucial for the recovery of the CLM deployer host in the event of a failure.

Note: The steps describe how to back up a CLM deployer host in a KVM virtualization environment; for OpenStack or VMware ESXi, see the RHEL or VMware documentation for information about how to restore a VM.

Steps
 
1 

Log in as the root user on the station that hosts the CLM deployer host VM.

2 

Open a console window.

3 

Enter the following to stop the VM:

# virsh destroy VM ↵

where VM is the VM name

4 

Enter the following to convert the CLM deployer host VM image in qcow2 format to conserve disk space:

# qemu-img convert -f raw -O qcow2 sparse_current_image raw_backup_image.qcow2 ↵

where

sparse_current_image is the name of the current VM image in sparse format

raw_backup_image is the name to assign to the backup VM image in raw format

5 

Enter the following to start the VM:

# virsh start VM ↵

where VM is the VM name

The VM starts.

6 

Store the raw_backup_image.qcow2 file in a location separate from the CLM system and preferably in a remote facility.

7 

Close the open console windows.
