vm blocked for failure veeam backup ""An error occurred while consolidating disks: msg.snapshot.error-DISKLOCKED."

case id -> #03863556
-------------------------
We have a production environment formed by a cluster 3 esxi with Vcenter 5.5 .We are using for backup Veeambackup & replication v 8.0.
The Veeam backup is installed in the same virtual machine of the vcenter.
Recently, we´had some problems with the backup jobs recently that affected some Virtual Machines.
In these virtual machines some files have been locked due to the backup failure, so I have the error in vm that says: "Virtual machine disks consolidation is needed"
When we try to make manual consolidation, the error that report us:
"An error occurred while consolidating disks: msg.snapshot.error-DISKLOCKED."
Unexpectly, cheking our vcenter we have recognized that the vcenter virtual machine has new virtual disks.
Checking The new vmdk Files of these new disks, we have seen that they are vmxd files of the virtual machines that are having these problems.
Attached part of the vmx file of our vcenter

where: server01, server02, server03, server04 and sever05 are the locked Virtual Machine.

Once we Turn off the Vcenter, if i remove the discs, Could it damage locked Virtual Machines?

What can i do to unlock them?

Thanks in advance.

Hi Juan, since your vCenter server is also a backup server, which is a proxy server by default, this is a result of the backup via hotadd where VM disks are attached to proxy server to read their data. You need to manually remove mounted disks from proxy and investigate the reasons why they were not dismounted after the job.
