delete folder with truenas nfs share not possible

[fabian3358]

Hello

I have the following problem I get error messages when deleting some files no matter Windows or MacOS.

When I want to delete a folder from a series I get the message that I should set write permissions even though I have them on other files I don't and on another series I get the message that it is in use even though it is not usable.

I have to delete it and download again only how can I delete it with NFS
