Hyper-V error 800700B7

Hyper-V failed to enable replication for virtual machine ‘xxx’ : Cannot create a file when that file already exists. (0x800700B7). Virtual machine ID 27bxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx

Replication scenario :

Consider my primary server is A and replica server is B. Replication is running A to B. There are one VM replicating from A to B. I have tried to resume replication both the VMs but replication is not resumed. So first i have removed replication from A and From B for those two VMs. Then removed VM from B and respective folder of VM (folder name on ‘VM ID’).

I am getting this error while i am enabling the replication again as it was disturbed so i need to re-enable it. But getting upper error. I have removed the replication and deleted the VM folder from replica. still it is showing as above and not enabling the replication.

The Solution:

Find in all folders on the destination server for the virtual machine ID:  “27bxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx”

I found one folder in :”Undolog Configuration” that can not delete , then I restart  the “Hyper-V Virtual Machine Management Service” and can delete it.

this is becose the partition was in GPT mode not MBR and in Hyper-V there are some problems:

this problem seems to be corrected on Windows 2012 R2:

the solution:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
x:\sources\recovery\StartRep.exe
This worked for me.
