Lower Limit for Image Garbage Collection

It specifies that image garbage collection will not be triggered until the available disk space drops below a certain percentage.

If it is set to a small value, there may be unnecessary and overly frequent image deletions, which will increase the system load. If it is set to a large value, unnecessary images may be retained for a long time, which will waste disk space.

Value Range

0–100

The value of this parameter cannot be greater than the upper limit for image garbage collection.

Default Value

70

Modifiable

Yes

Scope

CCE standard and CCE Turbo clusters

Suggestions

If disk space is limited and you need to save space, you can lower the threshold. If there is plenty of storage available, you can increase the threshold, which will result reduce system load by deleting images less frequently. Unless otherwise specified, keep the default settings.
