[issue36823] shutil.copytree copies directories and files but fails with that same directory with '[Errno 1] Operation not permitted')

[Ryan Avery]

New submission from Ryan Avery <ravery at ucsb.edu>:

I am trying to use shutil.copytree on an Azure VM that has Azure FileStorage mounted with SMB 3.0. When I run the following to copy directories from one location on my Azure File Storage to another location on my File Storage, the whole directory, subdirectory, and files are copied succesfully but then this errors on those very same files:

shutil.copytree(
    os.path.join(wflow.TRAIN, 'tile_512-4608'), 
    os.path.join(wflow.TEST, 'tile_512-4608')
)

Error: [('/mnt/point/landsat-1024-cp/train/tile_512-4608/image', '/mnt/point/landsat-1024-cp/test/tile_512-4608/image', '[Errno 1] Operation not permitted'), ('/mnt/point/landsat-1024-cp/train/tile_512-4608/mask', '/mnt/point/landsat-1024-cp/test/tile_512-4608/mask', '[Errno 1] Operation not permitted'), ('/mnt/point/landsat-1024-cp/train/tile_512-4608', '/mnt/point/landsat-1024-cp/test/tile_512-4608', '[Errno 1] Operation not permitted')]

After this error, all of the items listed above were actually copied so I'm not sure why this errors
