My network drive shows up in the file browser, just like my external usb-harddrive. Moving, running and editing files works. Hovering over it shows smb://lacie-2big/nasdisk .

BUT, when I want to save a file, the drive doesn't come up as an option. All I can see is my other places, including my usb-harddrive.

I am a complete newbie but I am GUESSING that it has something to do with the mount not being a "real" mount but just a shortcut to the smb location.

So I ran the tutorial at https://wiki.ubuntu.com/MountWindowsSharesPermanently about how to "mount a network drive permanently".

edited my fstab to

//LaCie-2big/nasdisk /media/nasmount cifs guest,uid=1000,iocharset=utf8,codepage=unicode,unicode 0 0

and running sudo mount -a gave me the following error:

mount: wrong fs type, bad option, bad superblock on //LaCie-2big/nasdisk, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount. helper program) In some cases useful info is found in syslog - try dmesg | tail or so

Now thats a very helpful error message, BUT, before I go any further, I'd be really thankful if one of you could tell me if I'm even in the right ballpark, or if my actual need: to be able to download files (ie torrents) directly to the drive, can be possible as it is already.

Question: How to fix "wrong fs type, bad option, bad superblock on //LaCie-2big/nasdisk, missing codepage or helper program" when running mount -a

I think you are on the right track.

Try without the codepage stuff, ( take out iocharset=utf8,codepage=unicode,unicode ). verify mount.cifs exist by running which mount.cifs as root.

Does the end of the output of dmesg show anything?

  • Thanks for the reply. Running mount -a now gives me: "error, could not resolve adress for LaCie-2big". I edited the fstab to have the path smb://lacie-2big/nasdisk instead, but that gave me the error "Mounting cifs url not implemented yet. Attempt to mount smb://lacie-2big/nasdisk

  • Ah, solved it now. I just replaced the lacie-2big part with the actual IP adress of the NAS and it worked. Thanks!

Check to see if mount.cifs exists as a command. If it doesn't, run apt-get install cifs-utils. Part of this package is the mount.cifs helper program that fstab uses.
