Dissolve and rebuild Hyper-V Cluster

Does anyone have instructions on the proper way to dissolve and then rebuild a cluster without destroying the VM’s (On a SAN LUN). Thanks I appreciate it!

Creating Linux VM’s using a kickstart script.

I need to build out some Linux VM’s (OL-7) and don’t want to manually add the networking/config info. There is already repository setup for bare metal linux hosts that will do what I want, but I’m not sure how to add the kickstart file to a new VM that is
booting up. My guess is to connect the virtual floppy, but I’m not sure where/how to create the virtual floppy using the correct format Hyper-V/Microsoft wants.

Has anyone done this before or have a good tutorial URL for this?

Thanks

Best way to reconfigure a 2016 failover cluster… Nodes and Cluster

Hi,

I have an operational cluster, but I need to rename the physical hypervisors and change the cluster name. I’v seen instructions on changing the cluster name, but what the best procedure seeing I need to rename the cluster nodes too? Thoughts?

Thanks

LUN Size

What size LUNs do you guys request from your storage team? When I worked with VMware I would request 5 to 10 TB LUNs. I obviously don’t want one massive LUN and I don’t was tons of small 1 TB LUNs so what’s your sweet spot?

Thanks

Windows 2016 – Failover Cluster – Quorum Question

If I do not dedicate a quorum drive in cluster manager what are the consequences? I have a 8 hosts cluster with 2 10TB’s LUNS attached as "cluster shared volumes" and everything (live migration, host failover) seems to be working just fine. I did
not designate a quorum or a witness during setup.

What am I missing?

Thanks

Firewall Ports – Hyper-V 2016

So in my setup I have a VLAN for the physical hypervisors and all the live migration/cluster functions and a separate VLAN where my application VM’s will reside. The two VLANs are completely isolated from one another. Which ports do I need to open between
the two VLANs so everything works (cluster, live migration,hyper-v) smoothly? 

I reviewed this and see Cluster Service listed at #5, but it doesn’t say how to implement them. Example.. Source would be hypervisors and destination would be application VM VLAN. I also see Hyper-V live migration, but again
not much detail.

Dynamic Disk

Has Microsoft published any recent best practices around using Dynamic Disks in Windows 2016 DC Edition w/Hyper-V cluster?

I’ve ready tons of conflicting articles about using them in just LAB,DEV,TEST, but never Prod. Some say Prod is ok after 2012. I found one that says don’t use Dynamic Disk in a cluster. Some say always use Dynamic unless the vendor recommends fixed. On and
on and on…

I just can’t find an "official" article from Microsoft that I can use to present to some colleagues.

Any help would be greatly appreciated.

Thanks

Virtual Switch Setup Question

Hi,

I was wondering how I should setup my virtual switch in a 2016 DC Edition hyper-v cluster (10 hosts) using failover clustering. I am using Hyper-V Manager at the moment.

I already have 2 8 gig FC cards dedicated to the storage so the remaining ports I have available are…

2 10 Gig E (currently teamed)

4 1 Gig E (I don’t want to use all four if possible)

* Currently host, Cluster, VM’s are all using the same VLAN. I can separate these by using separate VLANs if needed.

I currently have all (except storage) of the different functions using the teamed 10 Gig ports and it’s working just fine, but I guess best practices say to split the different functions (live migration, cluster, management, VM guest traffic) up. 

Would it be OK to just split the functions up using separate VLANs/internal/external switches and have any new VLANs trunked to the teamed 10 Gig ports? I would say 50-60% of the VM traffic will stay within the same 10 host cluster. Also live migrations and
or failover will be with the same 10 hosts.

I come from a VMware background and would normally just create one or two virtual switches with multiple port groups/separate VLANs and use 2 10 Gig E for everything except the storage.

Just looking for some advice/feedback from the community. : )

Thanks
