Shared Folder Mount

Walot · Post by **Walot** » 12. Aug 2008, 18:29

Hi, Host is Win XP Prof, Guest is openSuse 11.0, VBox is 1.6.4

nach langem Basteln I've got defined the shared folder in XP!? I'm not sure wether correct or not.

For mounting the shared folder in Suse I used a command line I found in a forum, which however was meant for UBUNTU. What happened shows the following protocol:

linux-3yfc:/home/WOSCH # sudo mount -t \vboxsf Brief-VB /mnt/Brief
mount: wrong fs type, bad option, bad superblock on Brief-VB,
missing codepage or helper program, or other error
Manchmal liefert das Syslog wertvolle Informationen – versuchen
Sie dmesg | tail oder so

linux-3yfc:/home/WOSCH #

dmesg | tail shows the following:

linux-3yfc:/home/WOSCH # dmesg | tail

Any idea what I have to change?
Thanks for help

Try the mount command without the \ after -t

. Run

Code: Select all

sudo mount -t vboxsf sharefolder /mnt/point

This is described nicely in the manual.

Hi Sasquatch, thanks for the answer but this I tried rightaway after the first one failed. I did it again today and you can see, the result is the same. I wundered wether the phrase ".run" in your example had been of any relevance and so I tried this as well. Again with no success:
-------
WOSCH@linux-3yfc:~> sudo mount -t vboxsf Brief-VB /mnt/Brief
mount: wrong fs type, bad option, bad superblock on Brief-VB,
missing codepage or helper program, or other error
Manchmal liefert das Syslog wertvolle Informationen – versuchen
Sie dmesg | tail oder so

WOSCH@linux-3yfc:~> sudo mount -t vboxsf Brief-VB /mnt/Brief.run
mount: Einhängepunkt /mnt/Brief.run existiert nicht
WOSCH@linux-3yfc:~>
-------
Any further hint?

The codepage might be a clue. Is this a charset issue. Do you have utf8 loaded? if not you may need to specify a different iocharset or convertcp parameter with a -o option.

Hi TerryE, either my English is to bad or my knowledge of Linux! I dont understand anything what you mean!!

If you can, explain it in German or more detailed please

It means that the character encoding used is not the same as the character encoding on the shared folder. If you for example use ISO-8891-1 on the Host, but mount it using UTF-8 on the Guest, you will get an error, or problems opening/saving files.

One thing I would do, is create a simple named shared folder, like "test", no upper case characters or other special characters. See if that works first.

Hallo Sasquatch, thanks for the explanation. I tried that as you can see, but the simple "brief" didnt help either. I renamed/recreated both host-folder and mount point:

linux-3yfc:/home # sudo mount -t vboxsf brief /mnt/files
mount: wrong fs type, bad option, bad superblock on brief,
missing codepage or helper program, or other error
Manchmal liefert das Syslog wertvolle Informationen – versuchen
Sie dmesg | tail oder so

linux-3yfc:/home #

fs type means file system?? In my case it is FAT32
bad option: I have no idea what option could be wrong or what other option could be used.
What is the "superblock" on my host-partition/folder?

annex:

About the character encoding: How can I compare or display the encoding types?

Post by **Sasquatch** » 17. Aug 2008, 20:49

The character encoding is one of the errors that's possible. If you read the error more carefully, you see that you have the following options as the problem:

Wrong filesystem chosen;
Wrong option chosen (though you didn't supply one, this is not it);
Bad superblock on the share (meaning cluster size in Windows terms);
Missing codepage or helper program;
A different error than mentioned above;

Now, are you sure it's a Shared Folder you set and not a network share? And does the mount point actually exists? You do have a folder /mnt/files? The location where you mount drives and shares have to exists, it cannot be created while mounting.

Hi,

in case

sudo mount -t vboxsf source /mnt

does not work and gives you

mount: wrong fs type, bad option, bad superblock on ...,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)

Try:

sudo /usr/sbin/mount.vboxsf source /mnt

It worked for me in openSuse(guest) on MacOSX(host).
