Problem to mount folder

Post by rafflo »

Hi,

I haven't had this mounting of folder from my Windows host into a Linux VM before, but now I get this in dmesg output:
[ 103.149592] 11:46:11.741661 automount Error: vbsvcAutomounterMountIt: Failed to mount 'SharedFolder' on '/media/sf_SharedFolder' because it is probably mounted elsewhere arleady! (-1,22)

In the VBox.log, it looks like this:
00:48:08.895118 SharedFolders host service: Adding host mapping
00:48:08.895135 Host path 'C:\Users\rafflo\Documents\SharedFolder', map name 'SharedFolder', writable, automount=true, automntpnt=, create_symlinks=false, missing=false

00:48:18.550818 GUI: Machine-window #0 deactivated

To mount folder, I've always went to Devices->Shared Folder->Choose folder and choose automount, and then it shows up in the gui in the Linux VM. This has always worked for me but now it doesn't. I tried rebooting, mounting other folders but same thing for every folder I mount.

Any ideas?

Yes. Have you investigated this:

Could be that the VM OS grabbed on for some reason and won't let go?

What if you don't automount the shared folder? Does the previous mounting point go away?
