アーチLinux。

私のNASにCIFSマウントがあり、フル権限でマウントされています。

# line from my fstab
//IP_ADDRESS/path/to/dir    /path/to/local/dir    cifs    uid=my_user,gid=my_group,dir_mode=0777,file_mode=0777,credentials=path/to/my/creds    0    0

ディレクトリの作成に失敗します。

mkdir path/to/local/dir/subdir
mkdir: cannot create directory '/path/to/local/dir/subdir': File exists

しかし、私が知っている限りいいえ存在する：

ls -la path/to/local/dir
drwxrwxrwx me me 0 date .
drwxrwxrwx me me 0 date ..

私のNASにあるファイルを見ると、サブディレクトリはリモートに存在しません。混乱しています。これを検索すると、ドットファイルが何であるかを理解していない人の結果がたくさん出ます。

何を提供しますか？

細部にちょっとした抵抗があったので（十分に公平だ）ここに精密コマンドと出力。これ/mnt/nas/SteamLibraryはNAS内のフォルダのローカルマウントポイントです。
