Hyper-V 2012 Cluster / Failover - supported? - Any known issues?

[Abhishek Gupta (LIS)]

Thanks again Karl! Yes, it should work. My understanding is that the failover should be agnostic to the guest OS but there could be some integration component that we might have missed. So it would be good to get to the bottom of this.

Regards,

Abhishek

Hi,

Manual fail-over appears to work OK - in order, I tested:

 - Live migration from one node to the other, and back again (worked)

 - Stopping the cluster service on one of the nodes (i.e. from Failover
Cluster Manager) - this showed the VM moving from the node that was
stopped, over to the other node (again worked).

 - Pulling the power on the active node hosting both VM's (i.e. Windows
guest, and FreeBSD guest) - this showed the remaining node trying to bring
up the VM's (of which Windows came up OK, and FreeBSD got corrupted).


I've had to stop now as the guy here looking after the Synology kit on the
test network is applying a firmware update (this is apparently for some
appletalk issue or something).

I'll re-run the test after this has been done - if it still fails, I'll
come back with a 'how to reproduce' type report (and I'll obviously let you
know if we can't reproduce it again!).

At least I know it 'should' work now :)

Thanks,

-Karl
