Left over Snapshots files for a VM, filling volume

When a cluster volume got too full Veeam B&R started to fail on the affected VMs. I have moved some VMs to a different Volume to test that they will back up in the correct circumstances, but most of the extra space (unexpected) that’s filled the volume
is for a specific VM which has a lot of snapshot files left after the backup. 

The VM itself is using AVHDX files instead of both its assigned VHDs.

Veeam Support told me to try shutting down the VM from Failover Cluster Manager (not the host OS) and that should merge the snapshots but this hasn’t worked. Veeam said that anything beyond that could involve data loss and I should call Microsoft.

My understanding is that the VM needs to be shut down and that the avhdx files need to be converted to VHD files in order to resolve this issue. I am also warned that simply removing the unused avhdx files will cause the VM to fail.

I have also noted that if I try and move this VM it is showing only the avhdx files that are connected to the VM, and not any of the parents which I see for each avhdx that I’ve inspected on this machine.

This makes me hesitant to move the VM in order to back it up. What should I do?

HPE Smart Path and Storage Spaces Direct

Hello Guys,

does anyone have a recommendation on enabling or disabling SSD Smart Path on S2D-Nodes?

I know that it should be disabled f.e. for vSAN.

Thanks!

a hypervisor has been detected. features required for hyper-v will not be displayed

I have a HP Proliant ML30 Gen10 and installed Microsoft Server 2016 Std. through the Intelligent Provisioning with Hyper-V. But after installation I cannot find the Hyper-V Management and in the System Information it says at the bottom: a hypervisor
has been detected. features required for hyper-v will not be displayed. I called HP Support and they said the machine is supported for Hyper-V and that I should get a fix (software) for this problem? The CPU is Intel Xeon E2124. I thought it was a BIOS setting
but HP said it was software related. Hopefully someone here knows the answer :-(.

iWARP RDMA not working on vNICs

In preparation for setting up S2D, I want to test the RDMA (iWARP) communication.
We use Qlogic QL41164HMRJ nics (Dell R640 - Server 2019).
RDMA communication works great (diskspd.exe) if I use the pNICs directly for this.
The counters in PerfMonitor give me positive results.

When using SET switch with vNICs it only works from vNIC to pNIC direction (SET and vNICs at the sending server, no SET at receiving server) not in the opposite direction (pNIC to vNIC). So, The vNIC does send RDMA traffic but can never receive it (Firewall
is disabled on both servers)

In the end, both servers must have a SET switch with vNICs of course

Any ideas?

No network connection between multiple VM’s

Hi folks hope you could help me.

Searched different fora but could not find a solution that was related to my problem?

Situation:
I have 2 network cards in my machine. 1 broadcom used by the machine itself (not used by hyper V)

I used the second networkcard (Intel i219-V Gigabit) as my "external network" in the switchmanager so i could communicate between 3 VM’s (server 2016) and a laptop hooked up directly with crosslink to the newtwork card.
All 3 VM’s use static Ip adresses, since 1 of the VM’s is a DC with DHCP on it and should give network adres to laptop. (That works fine)

Reason for that being that i’m studying for SCCM 2016 and i need to deploy to real machine for testing bios WMI query’s

Now my problem is that my connection between the VM’s is showing "no connection", but once i put power on the laptop and thus also on the external network then the virtual networkcards from the VM’s show connected.

This is really annoying since of course i want them also to be "connected" without the use of the external laptop.

There is also no hardware switch being used.

It’s like there is no virtual power on the virtual networkcards or no activity?
Hope i explain myself in a usefull way?

Hope someone could give me a permanent fix or a workaround.

Thanks
