What he is saying is that Disabling the Recycle Bin (trashbox) feature in the user interface does not work. There appears to be a bug. Once the feature is enabled on a share, you have to delete and re-create the share to make the Recycle Bin (trashbox) actually go away.
If I delete a file, it goes into the trashbox, which (of course) does not free up any diskspace. I checked the Share configuration and Recycle Bin is disabled. This is on a LS Pro 500GB.
I tried re-enabling the Recycle Bin and then re-disabling it. I delete files, then delete the trashbox, but it keeps coming back, even when it should be disabled.
I have a Media share with hundreds of GB of data, so deleting the share and re-creating it is not an option.
