Hi,

I've a big problem with VM Protect.

It's impossible to backup a vSphere 5.5 VM with CentOS 7 and the VMware Tools installed.

I get always an error as this :

Message: Failed to perform the operation with archive 'avfs:/smb?//xxx.xxx.xxx.xxx./Bkp_acro_prod/website.TIB'. Error: 'The group descriptor is corrupted.'.

If i remove the VMware Tools, i can backup the VM.

The tools are the same version installed than on a CentOS 6.

What can i do ?

Hey Nicolas,

I'm not with Acronis Support, but I do have a CentOS 7 guest installed on vSphere 5.5 and back it up often with no problems. One difference between our setups is I've installed the open-vm-tools package instead of the VMware Tools package, as is now recommended (I think there's even a warning about this during VMware tools installation).

I don't think there has been any updates of the VMware Tools since the release of RHEL/CentOS 7. As I'm sure you've been discovering, there are many important foundational changes between RHEL/CentOS 6 and 7, and I seriously doubt VMware would support such a setup. Have you tried installing the open-vm-tools package with yum?

Hi Ben,

thank you for your experience.

In fact, i've tested the two versions of the VM tools in mu CentOS 7 guest.

- Official VMware Tools installed through vSphere
- Open-vm-tools installed by yum

In each case the resultt of the backup is the same, failed after some seconds, with this :

Message: Failed to perform the operation with archive 'avfs:/smb?//xxx.xxx.xxx.xxx./Bkp_acro_prod/website.TIB'. Error: 'The group descriptor is corrupted.'.

But if I remove completely the tools, the backup is OK.

To be sure, i'm going to retry a backup with the open-vm-tools. No special config of them after the installation ?

Hi Nicolas,

The problem might have to deal with the specifics of the partition structure inside the VM (any specific LVM configuration?) alongside with the influence from VMware Tools version. It makes sense to contact our support team with the following information, so that we can try to reproduce the problem and suggest a possible fix for it:

1) Run the attached "systeminfo" shell script inside your Linux system to generate the system report (I've extracted it using the https://kb.acronis.com/content/1508 article)
2) Capture the backup log from Acronis Backup for VMware web console (View->Show Logs->Save All To File)
3) Please describe the virtual disks structure (type: thin/thick/independent/persistent, size, amount) of the affected VM
4) Confirm the VMware Tools version you are using in this VM (if possible provide a source link where you got it from)

Thank you.
