HyperV Checkpoints

[discoveranother]

Hello

 

I noticed one of the virtual machines has several checkpoints that need deleting, however when trying to delete it says

 

"An error occured while attempting to delete the selected checkpoint. Servername failed to remove the checkpoint.

 

Cannot delete checkpoint; Catastrophic failure (0X8000FFFF)

 

Virtual machine failed to generate VHD tree."

 

Any help most grateful.

 

Thank you

First check in hyper v manager that the checkpoint location is where all the checkpoint vhd are actually where they are located.

Secondly check that the checkpoint files actually exist as I came across something like this when I asked my tech to go thru and delete the check points. He deleted the actual files rather than the check points then shutting the vm down to allow HV manager merge the vhds. An operation I had shown him many times. What happens here is the checkpoints files become out of sync therefore they can not merge.

Bad news I am afraid if like me you don’t have HV backups of that server, I had to rebuild the server. Luckily for me it wasn’t a mission critical server

Good luck

Many thanks for your reply.

 

Yes I couldn't delete the checkpoints as mentioned. I tried exporting the last checkpoint and re-importing it, I tested this at home and it worked fine, but on premise, when trying to import the latest checkpoint it was taking forever. I had no option but to delete the VM completely from Hyperv Manager and add a new virtual machine from backup. It worked but I would rather have imported the latest checkpoint only. It was bit of a nerve-stopping moment as I wasn't sure if it would import ok, the last backup of the vhdx file that is.

 

Many thanks
