Today, I will talk to you about what to do if the CVM cannot be shut down. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can gain something according to this article.

When shutting down or restarting a cloud service, there is generally a low probability of failure. In the case of failure, you can check and deal with the cloud service as follows.

Possible reasons for shutdown failure

1. Check the CPU/ memory usage of the CVM. When the CPU utilization is too high or the memory is exhausted, it may cause shutdown / restart failure on the console.

The 2.Linux operating system can check to see if the ACPI hypervisor is installed, and command ps-ef | grep-w "acpid" | grep-v "grep" to see if any processes exist. If not, install the acpid module.

The 3.Windows operating system can check whether the shutdown failure is caused by too long WindowsUpdate, because when Windows does some patch operations, it will do some processing when shutting down the system. At this time, the shutdown may be caused by a long update time.

4. When purchasing Windows for the first time, the initialization process is a little longer because the system distributes the images in the same way as Sysprep. Before the initialization is completed, Windows will ignore the shutdown operation and cause shutdown / restart failure.

5. The operating system installs some software, or is hit by a Trojan horse, after the virus, the system itself is destroyed, which may also lead to shutdown failure.

Some cloud host vendors provide the feature of forced shutdown / restart, which can be used in case of multiple failed attempts to shut down the CVM. However, forced shutdown of the CVM may result in data loss or file system corruption of the CVM.

After reading the above, do you have any further understanding of what happens when the CVM cannot be shut down? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
