How do I manually cancel a disaster recovery task?

Solution

• Restart the virtual machine to quickly cancel the disaster recovery task.

• If the virtual machine cannot be restarted due to service constraints, follow these steps:

  1. During the backup, log in to the host where the virtual machine resides and run the following command to view the disaster recovery task:

     [root@localhost ~]#  virsh qemu-monitor-command UUID --pretty '{ "execute": "query-block-jobs" }'

  2. Run the following command to cancel the disaster recovery task:

     [root@localhost ~]#  virsh qemu-monitor-command UUID '{"execute": "block-job-cancel", "arguments": {"device": "zs-516"}}'

     The "device": "zs-516" parameter value is obtained from the query in step 1. If two disks are present, run the command twice and update the device value to the corresponding identifier for each disk.
