Hi Together
I try to take a backup of Hyper-V VMs (Windows Guests) using VSS.
Infrastructure:
HP ProLiant SE326M1 Shared Storage (Win Server 2012 R2) using SMB 2x HP DL380 G6 Hyper-V Servers (in Failover Cluster) The 3 Servers are Connected directly using 10 GBit/s.
Failover, Live-Migration, etc. works all without problem.
To be sure VSS works, I followed the steps described here on the storage serverhttps://technet.microsoft.com/en-us/library/jj612865(v=ws.11).aspx
-> A mistake on my side by configuration the storage is possible, but I don't know what i did wrong :(
Problem:
- If I try to perform a shadow copy (using DISKSHADOW) of a Hyper-V vServer operating on the SMB Storage, I got this error: the component microsoft hyper-v vss writer was not found in the writer components list.
- If I move the SAME VM to the local storage on the server (so the server is also not active in the Failover = Standalone VM) It works with the exact same commands.
The command vssadmin list writers don’t shows errors for the Hyper-V VSS Writer. The machines are up to date and rebooting don’t changes anything.
I hope some one has an idea :)
