Windows 10: Production Checkpoint on HyperV

We are despairing. We are desperately trying to create a production snapshot for our VM in the cluster. All drives including OS are shared drives. Any attempt to create the snpshot fails with the following error: "The checkpoint for "SQL-Koeln_***_***" cannot be created because at least one releasable VHDX is attached that is not part of the checkpoint collection. ID of the virtual machine: F12DD72D-24D6-46C3-B23E-40B3D********". The collection exists and all VHDS are also part of the collection. Unfortunately, although there are already several with such a problem, I can't find an

POWERSHELL HYPERV COMMAND TO EXPORT WITHOUT A CHECKPOINT

Hello,

I am trying to use a powershell command (Export-VM -Name PLEX -Path E:\hyperv) but it fails because it can't make a checkpoint. I have disabled checkpoints in the GUI of the hyperv manager itself but when trying to automated the task of an export this is
the issue I am running into. Hopefully it's an easy switch to add to the end of this command. Export-VM -Name PLEX -Path E:\hyperv.

 

Help with VM n Checkpoints pls!!


Can you detail the steps you took in creating a checkpoint?

 

HyperVisor doesnt merge checkpoint but doesnt show in manager

I have a server 2019 standard hyperv host with two VM's. For the last couple of months when my backup software - nakivo V10.5.1 - makes a checkpoint for backups the differencing disk from the checkpoint never gets merged. It does not show a checkpoint in the VMM manager but If I look at the Disk I will see the primary disk and the differencing disk.

For example:

TRINITYAPP.vhdx
TRINITYAPP.vhdx.mrt
TrinitApp.vhdx.rct
TRINITYApp_FFF2E652-A55D-4C12-A269-7C923754A49D.avhdx
TRINITYApp_FFF2E652-A55D-4C12-A269-7C923754A49D.avhdx.mrt
TRINITYApp_FFF2E652-A55D-4C12-A269-7C923754A49D.avhdx.rct

So the next time i try to take a checkpoint I get the error:

An Error occurred while attempting to checkpoint the selected virtual machine(s)
Checkpoint operation failed
Checkpoint operation was cancelled
TrinityApp could not initiate a checkpoint operation
Could not create auto virtual hard disk
E:\TrinityApp\TRINITAPP_E932BF12-4006-BA72-D6683D502454.avhdx: The process cannot access the file because it is being used by another Process

Because of this I am unable to use my backup software as it constantly fails because it can't take a snapshot

I have tried shutting down the VM and sometimes it will finish the disk merge but other times it will not.

I have tried shutting down and manually merging all the disks into one and building a new machine.

I have tried shutting down the vm and manually merging all the disks into one and removing the hard drive and readding it.

Every time I do something it may work a few times but ends up coming back to the error of being unable to create the checkpoint so the backup fails.

It appears that Nakivo is sending an API call to create the checkpoint to do its backup. Then it sends an API cal to tell hyperV it is done with the checkpoint and to delete it. And then it gives the error:

'TRINITYAPP' background disk merge failed to complete: The process cannot access the file because it is being used by another process. (0x80070020). (Virtual machine ID 05BFB8D6-1AC7-4F38-8DB4-FC26DE9CE49F)

Nothing I do seems to keep the error from coming back. Any help is appreciated.
