@zyzhang Yes you can delete an image through the web UI and it will delete it on disk as well. But you have to make sure you use the delete button in the image settings view - not the multi delete from the list view!
Mod added translation: Hello, the reason has been found, because the storage space of the fog server is full, and the image cannot be uploaded. Is it suspicious to delete the image on the web interface to delete the corresponding image in the storage at the same time, the fog version is 1.5.4
@zyzhang This is not a bug report! We need way more information. I am moving this to FOG problems.
