Removing the G5-Nodes from the cluster.

Hi  I am new to the Nutanix and want to know clarity on  below query.Please any body help me on below query,we have  a five  Nutanix node cluster and out of five node cluster three of them G5-Nodes which warranty will be completed on 31-oct-2023. reset of two nodes G8-nodes which we were added recently to the cluster.Now we are planning to remove the three G5-Nodes from the cluster and if we remove three G5-nodes,two nodes will be there and it become a two nodes cluster.if it is a two node cluster there no witness vm for redundancy. Now My Questions are below like. 1.       Is there any possibility of removing 3 nodes from the existing cluster?            A. Removing the 3 (G5) Node from the existing RF2 cluster is not possible. (2Node Cluster                         and  RF2 based cluster are designed for different Infra)            B. RF2 to 2 node cluster is not supported by Nutanix engineering Team.         2. What will happen after the License expires?          A. Replacement of h

Automating CLI commands

I’m looking into setting up an automated task to get the output ofacli snapshot.listfrom each of our clusters, so we can track down forgotten snapshots & which VMs they’re on.Ideally this would run from nutanix itself and spit out the results into some kind of shared storage space we can review, but according to this thread, non-default cron jobs are deleted when AOS gets upgraded. I also can’t see anything in PC/PE to automate this, or find this information without SSHing into the CVMs.At this point, I’m looking into writing a script to host somewhere internally that SSHs into each set of CVMs and runs the command, but then I’ve got to handle password security and frankly it seems like too much of a bother for something I’d only have running monthly at most, that would take me 10 minutes to handle manually (if I remember) Does anyone know of a way to achieve this, or shall I just throw some reminders on my calendar?

Nutanix networking

what is the difference between these, can anyone share the refernce diagram for these 2 scenarios4 × 10 GbE (2 + 2) and 2 × 1 GbE separated Use to physically separate CVM traffic such as storage and Nutanix Volumes from guest VM traffic while still providing 10 GbE connectivity for both traffic types. The four 10 GbE adapters are divided into two separate pairs. Compatible with any load balancing algorithm. This case is not illustrated in the following diagrams. 4 × 10 GbE combined and 2 × 1 GbE separated Use to provide additional bandwidth and failover capacity to the CVM and guest VMs sharing four 10 GbE adapters in the same bond. We recommend using LACP with balance-tcp to take advantage of all adapters. This case is not illustrated in the following diagrams.

GPU Pass Thought Node Upgrade (Feasible or Not)

There is a cluster using GPU pass-through. It consists of 11 nodes, including 3 GPU nodes. Servers utilizing GPU pass-through are billed servers and should ideally have minimal or no downtime.Due to the current End of Service Life (EOSL), an upgrade is being considered.For this, the plan involves excluding one GPU node from the cluster, upgrading it to AOS and AHV standalone. Then, using cluster expansion to add it back, turning off the power of the GPU pass-through server, migrating it, and subsequently upgrading the remaining nodes through LCM.Is this plan feasible?

Cluster Failure on Old Environment

Hello Everyone,We have a cluster that failed. It’s running on an old NX-G5 box, and has been out of support for a while now. When trying to start the cluster, we’ll get varying messages. Sometimes it’ll say the cluster hasn’t finished being configured. Other times it’ll be about genesis or zookeeper. Genesis is currently running on all the CVMs, zookeeper is only running on one of them. I’m able to ping everything from everywhere, and all of the zookeeper and network config files look correct. Any ideas on what to check from here would be greatly appreciated.Another thought was that if we couldn’t get the cluster up and running, is it possible to somehow recover the VM disks and import them into another AHV cluster? Does anyone have any experience with this?

Does AHV support creating external snapshots?

I have a virtual machine that created a snapshot. After logging into the CVM, I can find the disk files corresponding to the snapshot in the snapshot directory. However, the size of the snapshot file is equal to the size of the master disk, which is a complete replication, not generating a new file to store the increment. I added a file to the virtual machine and found that the modification was to the master disk, while the last modification date of the snapshot file did not change.The underlying layer of AHV uses kvm, which can create an external snapshot through virsh.Does AHV support creating external incremental snapshots

Does Nutanix CE support disk block tracking

Does the Nutanix SDK include an interface for downloading disk content?Does the SDK have an interface for obtaining incremental data based on snapshots? Just like the Esxi SDK of vmware, disk data can be downloaded through SDK, and after taking a snapshot, incremental and differential data can be obtained by comparing the snapshot with the previous snapshot or master disk

Self-Signed certificates from prism

Hi I’ve created certificates on a local CA for my two prism servers and prism-central. However it looks like the certificate update only applies to Prism Central. I’m using cvm-london and cvm-midlands as alternate names on the cert but the prism pushes out its own certificate. Is this expected?

AHV 100GB Networking Support

We got a couple of servers with 2 x Dual Port 100GB Ethernet Adapters and 1 x Dual Port 10/25GB Ethernet Adapter, I need some clarity if AHV supports uplink speeds of 100GB. From the documentation I’ve been reading on the support portal, it mentions that AHV cluster networking only supports 10, 25 and 40GB (https://portal.nutanix.com/page/documents/solutions/details?targetId=BP-2105-Linux-on-AHV:nutanix-ahv-cluster-networking.html). Does this mean that those speeds are only for AHV / AOS and a separate bridge can be created with the 100GB uplinks for the virtual machine traffic?

Windows 10 vTPM not working

Dear community,We are facing a weird issue regarding vTPM and already opened a support case without much luck.Our cluster is fully updated and we are even using PC 2023.x build.If we create a new Windows 11 22H2 virtual machine, the “Get-TPM” cmdlet works fine and BitLocker can be enabled.If we do the same but with Windows 10 22H2, the cmdlet fails, which means we can’t use the additional security features like BitLocker or even upgrade to Windows 11.Have you ever seen something similar?Many thanks!Bruno Martins
