The OMV documentation on Shared Folders does not cover the behaviour of the "Delete" operation.
One would expect that deleting a shared folder will delete the corresponding subvolume, hence the data.
However, a shared folder is not always a subvolume, as one can share the whole disk by setting the relative path equal to "/".
Under this circumstance, will deleting the volume root "shared folder" affect any of the subvolumes?
Will it affect files on the root of the volume, that do not belong to any shared folder (subvolume)?
It would be nice if this could be clarified (even better, if the documentation can be updated).
