Can not consolidate on free hypervisor :(

DDear All,

I have a problem with consolidating. I have a vm, it has an ssd disk and a hdd disk. On the SSD partition there are eight "vmname-00000x-sesparse.vmdk and vmname-00000x.vmdk" files, on the hdd partition there are two "vmname-00000x-delta.vmdk and vmname-00000x.vmdk" files . When i tried to consolidate the web page shows an error: "Disk consolidation for VM_name has failed: Unable to access file since it is locked"

Key : haTask-15-vim.VirtualMachine.consolidateDisks-133004238

DDescription  Consolidate disk files of this virtual machine

State Failed - Unable to access file since it is locked

Errors

• Consolidation failed for disk node 'scsi0:0': Failed to lock the file.
• Consolidation failed for disk node 'scsi0:1': Failed to lock the file.
• An error occurred while consolidating disks: Failed to lock the file.

When I try to search the problem, I see in the vmware.log in the vm's folder, that the problem start with:

failed to lock file vm_name-flat.vmdk

then failed to lock file vm_name.vmdk

It shows vm_name.vmdk failed to open with flags 0x20a ; failed to lock file (16392)

I tried to check with the vmfsfilelockinfo -p <files>, that show all the files locked by the virtual machine itself

When I tried to check with the lsof, I see that the second delta file locked by two 'things'

The vm has has the cartel id 562811.

[root@:/vmfs/volumes/.../vmname] lsof | grep 'vmname_1-flat.vmdk'

562811      vmx                   FILE                      128   /vmfs/volumes/.../vmname/vmname_1-flat.vmdk

[root@:/vmfs/volumes/...9/vmname] lsof | grep 'vmname_1-000002-delta.vmdk'

562811      vmx                   FILE                      126   /vmfs/volumes/.../vmname/vmname_1-000002-delta.vmdk

562811      vmx                   FILE                      129   /vmfs/devices/deltadisks/2c50c6f-vmname_1-000002-delta.vmdk

[root@:/vmfs/volumes/.../vmname] lsof | grep 'vmname_1-000001-delta.vmdk'

562811      vmx                   FILE                      127   /vmfs/volumes/.../vmname/vmname_1-000001-delta.vmdk

I don't dare to restart the machine (to keep the running state), however I would like to get rid of those sesparse and delta files. Is there any way to get rid of them? Using the free hypervisor tools?

Thank you very much
