I’m trying to use Windows Server Backup on a Windows Server 2019 Standard with Hyper-V, but it gives me errors.

This is the message from Windows Server Backup:
"Backup succeeded but some components backed up were inconsistent in the snapshot. The application this component belongs to might not function properly after this backup is used for recovery."

And this is the message I get in Event Viewer for each VM that is online during the backup:
"VSS writers inside virtual machine ‘*****’ failed to perform BackupComplete to its shadow copy (VSS snapshot) set: A function call was made when the object was in an incorrect state for that function (0x80042301)."

Any suggestion on how to use Windows Server Backup for our Hyper-V VMs?

I am planning to test install the latest Hyper-V core on a DELL R6415

( 17763.557.190612-0019.rs5_release_svc_refresh_SERVERHYPERCORE_OEM_x64FRE_en-us ) 

I do notice that there is a known issue mentioned with recent DELL EPYC servers, to wit :

"

To
install Windows Server 2016 RTM using the operating system (OS) installation media:

1. Press F2 during the POST to access System Settings and disable Virtualization Technology in the Processor settings.
2. Install Windows Server 2016 with the OS installation media.
3. Apply the latest Update Rollup via Windows Update. Windows Server 2016 RTM requires a hotfix (available on June 2017 Update Rollup and later) for a known AMD IOMMU issue. Deployments after Windows Server version 1709 no longer need this hotfix.
4. Go to System Settings (F2 during the POST) and enable Virtualization Technology in the Processor settings.

"

Is it safe to assume that this is already fixed in 17763.557.190612-0019.rs5_release ??

Has anybody here successfully  installed Hyper-V2019 on an EPYC server?

TIA!

Hello,

Our backup team is reporting issues backing up two servers.  When checking the servers I am unable to take new checkpoints from either HyperV manager or SCVMM.  From HyperV manager if I go to settings and change the checkpoint type from Production
to Standard I am able to take checkpoints, however the backups are still failing.

I’m fairly certain that the issue is related to the fact that even though the VM does not appear to have a checkpoint if I look at the properties of VM it appears that the first disk does not have a checkpoint while the other two do:

Is there a way to force these checkpoints to merge?

Hi,

IP address is set on Hyper-V host machine. When I try to query it using the following SCVMM command, IPAddress field in the adapters is empty.

 Get-SCHostNetworkAdapter -VMHost $vmRef.VMHost 

Has anyone faced this issue earlier? Is there any way to fix this issue? 

Thanks,

Priya

I have a 2019 server (new clean install) and am trying to install wsus from the server manager gui.

All goes well until post installation tasks and I get: "Fatal Error: Failed to start and configure the WSUS service"

When I look at the log I see (amongst other things):

2019-08-16 09:47:33  CreateDefaultSubscription failed. Exception: System.Net.WebException: The request failed with HTTP status 503: Service Unavailable.

Any ideas?

Hi all,

Hoping someone may have ideas on how to resolve this one!  We have a 2-node cluster (HPE ProLiant DL360 Gen10) built on Windows 2019 Standard GUI, iSCSI to Nimble storage.  All validation tests pass with flying colors!  When we were testing,
i.e. with very little load we had one instance of a 2019 VM (vm version 9) which got stuck in a ‘stopping-critical’ state when rebooting.  At this point, the host has gone ‘awol’ with cluster functions, from then on any cluster operation failed until
the host is rebooted (draining would never finish, any other live migration times out and fails).  We found that we had a switch down so put it down to that (even though redundant paths were AOK).  Since then it has been working beautifully as expected,
I’ve done plenty of migrations, draining of hosts without issue, until yesterday.  The client decided to patch a Window 7 VM, it rebooted and got stuck in the same fashion, Stopping-Critical.  I have tried the trick of killing the VM process, this
does not work in this scenario.  There is nothing we can do except cold boot the server, forcing failover to the other host.  Obviously a bit of an issue as the 30 servers now running on there restart on the other host, interrupting file / print
services etc.

I’ve read about disabling VMQ but I really don’t want to go disabling the advanced performance features unless we absolutely have to.  I am using Dynamic memory on most of the machines, otherwise pretty standard configurations.

No issues with resource we are using under half memory on both hosts.

Any ideas?

Thanks,
Simon
