Ich habe eine externe Festplatte an einen ASUS-Router angeschlossen, der einen Samba-Server implementiert. Alles funktioniert einwandfrei, bis auf eine nervige Sache: Das Erstellen eines Verzeichnisses mit mkdir gibt eine Fehlermeldung zurück, obwohl das Verzeichnis tatsächlich erstellt wurde.
Die entsprechende Zeile in /etc/fstabsieht folgendermaßen aus:
//192.168.1.1/data /media/external/data cifs username=data,password=data,vers=2.0,uid=1000,gid=1000 0 0
Beim Einhängen der Festplatte ist alles in Ordnung. (Das Verzeichnis stackoverflowbefindet sich auf der externen Festplatte.)

Beim Erstellen des Verzeichnisses testwird eine Fehlermeldung angezeigt.

Das Verzeichnis wird jedoch erstellt!

Daher frage ich mich, ob das Problem darin besteht, dass mkdir das gemountete Verzeichnis aus irgendeinem Grund nicht "sieht" und eine Fehlermeldung ausgibt, als ob Sie versuchen würden, ein Unterverzeichnis in einem nicht vorhandenen Verzeichnis zu erstellen.
Aber warum ist das so? Was kann ich tun, um das Problem zu beheben?
(Ich will hinzufügen , dass , wenn es mit Montage vers=1.0, die mkdir Fehler nicht zeigen. Allerdings file_modeund dir_modedann ignoriert zu sein scheinen, und ich brauche sie eingestellt werden , 0700in einer anderen Anwendung.)
Update: Wenn der Datenträger an den USB-Anschluss des Computers angeschlossen und NTFS gemountet ist, funktioniert alles einwandfrei.
