How a file is created determines the initial state of the file. For example, a file created in an NFS export will likely be POSIX, while a file created in an SMB share will be in ACL. If a file was migrated to PowerScale OneFS, the migration tool affects the file state. Additionally, configured policies also determine the file state.
Initially, the file state is dictated by how it is created or copied, but the directory structure can also affect the file state. Thus, the file state depends on the workflow and directory structure. For example, if the parent directory has inherited ACL(+) and the file is created through NFS, the file will be in ACL state. The same also applies if the parent directory is POSIX mode. If a file is created through SMB, the file state is POSIX mode.
