If the Windows system fails to create a custom image, you can troubleshoot the issue as follows:
No. A custom image can be created from the system disk snapshot, but not from the data disk snapshot.
If you need to keep the data on the data disk of the original instance when launching a new instance, you can first take a snapshot of the data disk, and then use this data disk snapshot to create a new CBS data disk. For more information, see Creating Cloud Disks using Snapshots.
/etc/fstab
file.mount
command to query the mounting information of all devices. Ensure that the execution result does not include the corresponding data disk partition information.Yes.
Yes. You can continue to use the original custom image after changing the operating system.
Yes. You can upgrade all of them. For more information, see Change Instance Configuration and Adjust Network Configuration.
No. A custom image can only be used in the same region. For example, you cannot directly launch a CVM instance in East China (Nanjing) using the custom image created from a CVM instance in East China (Shanghai).
To use a custom image across regions, copy the image to the target region first. For more information, see Copying Images.
You can view the image creation progress on the Images page of the CVM Console. The time it takes to create an image depends on the size of the instance’s data.
