Hyper-v 2012 R2 checkpoint fails

Hi all,

Need some advice please.

When trying to make a checkpoint on a virtual machine (only happens to this one) I get the following messages:

'My VM' could not initiate a checkpoint operation: The directory or file cannot be created. (0x80070052). (Virtual machine ID 5E4B7C4C-6F95-498D-BDA5-AF917B0D4B5B)



'My VM' could not create auto virtual hard disk C:\ClusterStorage\Volume6\My VM\My VM_disco_E_CA282C1F-35FE-4928-B56D-80C4C1C938B5.avhd: The directory or file cannot be created. (0x80070052). (Virtual machine ID 5E4B7C4C-6F95-498D-BDA5-AF917B0D4B5B)

thanks in advance

Miguel
