Can't mount shared folder after upgrade to 3.1.0

[Kakao]

Windows XP host. Fedora 12 64 guest.

After upgrading from 3.0.10 to 3.1.0 I cant' mount the shared folder anymore. I did reinstall Linux Addtions after upgrade.

Code: Select all

# mount -t vboxsf Downloads /mnt
mount: wrong fs type, bad option, bad superblock on Downloads,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
# dmesg | tail
sf_read_super_aux err=-22

I have the same problem with OS X (Leopard) host, and Fedora 11 (64 bits) guest, with the same error.

That error usually means that the SF module isn't installed properly. Please install the GA again and see how that goes.

Reinstalled and the problem persists.

Hello everyone,

I'm experiencing the exact same problem.
Host: Windows 7 Professional 64 Bit German
Guest: Fedora 11 64 Bit.

Reinstall didn't work either.
Any help would be greatly appreciated.


Thanks in advance,

Having a similar problem here. I can mount shares if i I do it manually, but they no longer mount at startup via my init.d script. I did get a strange error when I tried to install the GA, something about having an old version (not helpful, I know). To those of you having trouble mounting even manually, try repairing the GA's:

Code: Select all

sudo /etc/init.d/vboxadd setup

Anyone have an idea as to why I can mount manually, but not during startup? The script worked fine until I updated the GA's.

Hello Raere,

I've tried that and sadly it didn't work.

btw. "dmesg | tail" (as recommended by the error message) brings up the following.

Code: Select all

[user@fedora11 ~]$ dmesg | tail
sf_read_super_aux err=-22
sf_read_super_aux err=-22
sf_read_super_aux err=-22
sf_read_super_aux err=-71
sf_read_super_aux err=-22
sf_read_super_aux err=-71
sf_read_super_aux err=-71
sf_read_super_aux err=-71
sf_read_super_aux err=-71
sf_read_super_aux err=-22

and when I add "-o uid=##,gid=##" to the mount command I get a protocol error (no, share and mount-point are not named the same).

Edit:
# rpm -qa | grep vbox
doesn't output anything, shouldn't the guestaddons be brought up here?

No solution for the people having trouble mounting manually, but I figured out why my shares weren't mounting on boot (does anyone else actually have this problem after upgrading to 3.1.0 as well?) In init.d, the share script was set to run before the vboxadditions module was loaded. I just changed the script to run after the vboxadditions module, and that fixed it. This is all on Ubuntu 9.10 server, by the way.

Well usually you would use rc.local to load these mounts. I used to use fstab but that was not correct.
Try to mount them using rc.local and see if this works.

Hello again,

I still didn't have any luck in mounting a shared folder. Anyone else got a good idea? It's very annoying having to upload every file to my ftp in order to re-download it from within the box (if I don't have a thumb drive handy).

Any suggestions would be greatly appreciated!

Same problem here... Tried everythin, nothing worked... HELP NEEDED! Thanks!

I have the same problem. I am using Mac OsX as host and Fedora 12 as guest.
My /sbin/mount.vboxsf is a link to /usr/lib/VBoxGuestAdditions/mount.vboxsf which does not exist.
Where can I find mount.vbox.sf?

What I am doing is to connect to the host using Nautilus (Fedora guest) "Connect to Server..":
1. Open Nautilus.
2. Go to File -> Connect to Server...
3. As the service type chose Windows Share.
4. Enter the Host's network name or IP address.
5. Enter any optional information.
6. Click on Connect.

Edit: If your guest don' t have a similar graphical solution try samba client configuration.

[culicidae]

I solved the problem (at lease for my machine)!

Despite installing the GuestAddons for 64 Bit OS (Fedora 11 in my case) the link in /sbin/mount.vboxsf points to /usr/lib/... where it should be /usr/lib64/

Hope that helps!
