Hello,
For someone who can help me on this very strange issue:
Our environment: Hyper-V Cluster with hosts running w2012 R2, Virtual Machine Manager 2012 R2 to manage virtual environment, SAN storage that provide LUNs where CSVs are stored, and virtual machines running Windows 2008 R2.
Yesterday, a commont task such as converting vhdx to fixed from VMM2012R2, has generated an error on that vhdx that has put it completely unavailable. That are the steps were done:
- with the vm stopped, from VMM i edited the properties of one of the virtual disks connected to that machine, and selected to convert to fixed
- i started the proccess, the job began to do the task and about at 50% of the process the task ended in VMM with the error:
Error (2909) VMM cannot create the file C:\ClusterStorage\VolumeX\....\efpljdkr.vhdx because the file name already exists on the hyfbdst26.dmndst.loc server. Cannot create a file when that file already exists (0x800700B7)
- The VM was unavailable, only with the repair option active. I executed a repair with "ignore" option, and VMM returns the same error.
- In the LUN where de vhdx disk is stored, there was the temp file efpljdkr.vhdx created by VMM
- I deleted the temp file, i tried to repair again the VM with the "ignore" option and the VM became available again, but wen i started it the VM showed an error as the vhdx was inacessible.
The vhdx disk is stored on the lun but actually is unavailable: i have no permission to edit, rename, copy, show security acls, etc... despite of i am domain administrator. I can't view security properties of the file...
if i execute powershell command "Get-Acl name.vhdx" i obtain error: Access is denied.
I can not get ownership of the file. The file is completely isolated from somehow security reasons
Can anyone help me with this strange error please?
Thanks in advance!
