I'm just bruinging online my new Hyper-v failover cluster on 3 DL380.
this cluster is using shared storage that's supplied by a CiB from DataOn, storage is made availeble using storage Spaces.
storage cluster (csv) talks to the Hyper-v cluster trough 10gbe nett (failover through 2 mellanox switches)
All this works great. i got 80 something servers on this setup. And VEEAM 9.5 release3 works great.
Inside this setup i got 2 windows2016 servers that are clustered and use a VHDS disk set as shared storage, they supply the fileserver role. This works great.
Now the backup

I take a backup of this cluster and smoothed out the iniatial errors.
I setup a backup job that takes backup of both servers in the cluster one of them sails through perfect the other one it seems that the backup job doesn't see the disks or can't access them.
Is this the right way to backup up a cluster with a shared disk (VHDS) ?
looking forward to some input
