Hello Experts
i need some advise on best way forward to setup a 3 node hyper v failover cluster using windows server 2016.
I got 3 Dell Servers all identical config,  and 1 dell SAN storage. 2 Dell iSCSI 10GB swithces,  2 Cisco c3750 switches, 1 dell server to act as standalone DC.

i have been doing 2 node clusters in past but never done a 3 node cluster. so need some advise on network config as in 2 node cluster i used to connect two servers via direct crossover cable for cluster heart beat etc and use cluster quorom disk .

so any tips will be much helpful.

thanks
Harry

14 Hyper v hosts, managed via SCVMM running on a c7000 blade chassis with 10G interconnects - All intel CPU's, 192 GB RAM etc. Broadcom nics but vmq disabled.

Dell 10GB switch managing ISCSI to the chassis and SAN.

IBM v3700 with 2 expansion trays.
5x400GB SSD's in raid 10 for easy tier, 4 x raid raid 6 arrays of 10k disks. (lets call it 8 disks each array) 1 x large Raid 6 of Nearline drives.

The environment is well loaded and runs fine running a varying number of VM loads.

We monitor extensively all performance etc and know that there are no issues with CPU, memory or disk access etc UNTIL:

If a backup is misbehaving, someone is doing a high disk load activity or something like deploying a templated VM, all users across all VM's notice a slowdown or lockup.

DISK IO on the SAN is neligable, Ram usage, CPU Usage does not spike and there only a small increase in the amount of network traffic.

It seems like everything runs well, but just a small event can cause issues.

Looking for ideas, configuration changes or otherwise.

We have a two server boxes in a HA Cluster setup

When a node is shutdown, the VMs on that node are not appearing /migrating to the other node thats in the HA cluster.

When both nodes are on, VMs can happily migrate from node to node without a problem.

Why is this ?

I have a Hyper-V Manager in a workgroup on 192.168.5.254 and a Freecom NAS drive on 192.168.5.30. Both are in a workgroup called JGL.
When creating a new VM I point the .iso location to \\192.168.5.30\Software\server2016.iso which it accepts but when I click finish I get the error:

From Windows Explorer I can map to \\192.168.5.30\Software and I'm prompted for a username and password and I click "remember" (subsequent connects don't require credentials)
I can't see anywhere in Hyper-V where I can enter credentials.

I have a Windows 2016 Hyper-V manager with two guest VMs. One guest VM is a Domain Controller and the other is a SQL DB server which is a member of the domain.
The Hyper-v server is in a Workgroup. Should I make the Hyper-V server a Domain Controller for a separate domain and then make resources such as a NAS, members of that domain?
I'd like to access the NAS from the Hyper-V manager for VM builds and Disaster Recovery and I'd also like to access the NAS from the Guest VMs for software images.

I keep getting the following error when creating a cluster on Hyper V

An error occured while creating the cluster and the nodes will be cleaned up.
Please wait...

There was an error cleaning up the cluster nodes. Use Clear-ClusterNode to manually clean up the nodes.

An error occurred creating cluster XXX-XXX-XX Cluster.

Patch levels and networking are all sound.

Using Server 2016 Hyper-V, I'm comparing Dynamic vs. Fixed Disks using 10,000 RPM SAS drives and a Dell PERC H730.  
I have currently set all four partitions on the two VM's to dynamic disks but wondering if it is worth the effort to convert them all to fixed disks.
The partitions are all using VHDX files (two partitions for each VM--operating system and data for each).   According to this web page, dynamic disks are actually faster in "overwriting" than fixed disks so perhaps I should keep the disks to dynamic:

Thank you.

I have a management console on a Windows 7 VM. I need to create on for a new site. The software is exactly the same, just needs a IP change and a few configuration changes to create on for a new site. Can I copy the VM I have an reconfigure it for the new site. It will set on the same Host. I know how to import and export the VMs but not sure what I need to do for the domain to see it as a new PC. Please advise. We use Windows Server 2012 R2 standard and Hyper-V.

New creating VMs so any recommend links would be appreciated as well.

I was reading the above mentioned article, and it appears to suggest not using dynamic disks if at all possible.  It suggests not using dynamically expanding disks because of reduced performance by increased overhead and fragmentation.

I usually assign the guest VM OS as a fixed disk.  This also applies to virtual disks with databases.  However, for growing company file storage, I usually assign the virtual disk as dynamically expanding with a cap imposed.

I will be installing a new Windows 2016 hyper-v server with two vms.  On one of the two vms I was going to assign the guest os (80Gbs) and a database virtual disk (150Gbs) as fixed virtual disks.  Their company data is currently at 330Gbs, and growing, and I was going assign it as a dynamically expanding disk with a cap of 800Gbs.   As a rough estimate the amount of disk space will probably double within 4 or 5 years.

After reading this article, I may want to consider assigning this virtual disk as fixed (800Gbs), and be done with it.  I understand, a large fixed disk has drawbacks when it comes to moving/restoring the entire drive should that be necessary.  However, fragmentation is just as an important issue over the near/distant future.  Also, I purchased this server with a more than adequate amount of overall disk space to last many years, so disk space is not …

I would like to know from expert who have experience to convert physical server which is running window server 2018 r2 to hyper-v 2016 virtual machine .

I check on the hyper-v 2012requirement the guest machine is atlease window server 2012.

Hello,
I have 2 windows 2016 hyper-v hosts in a workgroup and I plan to join those 2 hosts to domain.
Hosts have 2 DCs(2008r2) as a guests VMs and couple other member servers.
Reading this article I dont expect problems running DCs on domain joined hosts
https://www.altaro.com/hyper-v/demystifying-virtualized-domain-controllers-part-1-myths/
Should I expect any problem if I join hyper-v hosts to domain?
I plan to shutdown guests VMs and join host(s) to domain and than power on guest VMs.

Using Windows 2016 Hyper-V I have created a couple of VMs and a Test VM so that I can prove my backup and restore process.
I have successfully backed up my Test VM and so have now deleted it using the Hyper-V Manager. Using Windows Explorer I have also deleted its associated Test.vhdx file. However, there are some .VMRS files that I can't delete because they are in use
How can I remove these files

I have converted 3 Physical servers (server 2012 R2) to VMs using P2V program. I have now got all 3 VMs up and running in hyper-v (server 2016). I have created a virtual switch and  attached the VMs to it. It is configured as an external virtual switch so that the VMs can communicate with the rest of the network.

The problem is I cant ping anything. I cant even ping the hyerp-v hosts ip address?

I have created a fresh virtual switch and still nothing,

All the VMs are configured with static ip addresses.

Any ideas?
