Description:
After updating virtualbox-guest-modules-arch package to version 5.2.2-1, VeraCrypt (current version: 1.21) is not able to open encrypted file containers on shared folders any more. It tells me
"I/O error:
/dev/mapper/veracrypt1
The drive is damaged (there is a physical defect on it) or cable is damaged, or the memory is malfunctioning."
I can open the same container with the same VeraCrypt version on the Windows 10 host without any problem.

Environment:
My arch installation is inside a virtual box vm. Therefore I have the current guest modules packages installed.
My arch vm has shared folders to the host OS (Windows 10). On one of these shared folders there is an encrypted file container that should be decrypted / mounted with VeraCrypt.
* Guest OS: arch installation: Updated everything to current package version in repos (2017-11-29)
* Host OS: Windows 10 with virtual box Version 5.2.2 r119230 - latest official version

Workaround:
I found out that if I downgrade the virtualbox-guest-modules-arch to version 5.2.0-5 (I used the package from my pacman cache: virtualbox-guest-modules-arch-5.2.0-5-x86_64.pkg.tar.xz), the problem went away. As soon as I update to later packages (virtualbox-guest-modules-arch-5.2.2-1-x86_64.pkg.tar.xz or the latest package virtualbox-guest-modules-arch-5.2.2-4-x86_64.pkg.tar.xz) the problem occurs again.

Steps to reproduce:
* Boot the arch linux inside the virtual box VM
* open VeraCrypt
* Try to mount a VeraCrypt container that is located on a shared folder between the arch guest and the Windows 10 host
--> Error message occurs (see screenshot).

If you need further information, please don't hesitate to contact me.

well this is not a VeraCrypt problem but you kernel in the VM is bound to a specific version. its either that you have not rebooted after a linux kernel update or the virtualbox-guest-modules-arch in the non testing repo is not build against the latest kernel in non testing repo

5.2.0-5, 5.2.2-1, and 5.2.2-4 were all built against the latest kernel in Core and should work; anthraxx was assuming something different.

He's right that it's not a veracrypt problem, though. Did you load the new modules after updating the package? If so, it would appear to be a vbox problem.

Edit: Assuming the modules actually loaded without an error, of course.

How can I check if the module is loaded?

30 seconds with google should turn that info up easily

Thank you Dough, I can type lsmod. My question was, if you need further information or log files too see possible subcomponents states...

lsmod with virtualbox-guest-modules-arch-5.2.2-4-x86_64.pkg.tar.xz / virtualbox-guest-modules-arch-5.2.2-6-x86_64.pkg.tar.xz installed:
lsmod | grep vboxguest
vboxguest 229376 5 vboxsf

virtualbox-guest-modules-arch version 5.2.2-6 has the same problem (virtualbox-guest-modules-arch-5.2.2-6-x86_64.pkg.tar.xz). Of course I did a consistent upgrade of all repositories today including the new kernel 4.14.

Sounds like Oracle decided to clean up and removed code that they thought is unused, legacy stuff or whatever.
I guess opening an upstream bug report is the way to go.

I do not think there is anything we can do here.

Possibly related to changeset 69149?

I did not take a detailed look though.

@Daniel.Schmidt
Is this still an issue? Any update?
