Query Cluster Name From Guest

Hi,Is there a way to query which cluster that a VM is running on from within the VM itself?   I will need this for both Windows and Linux VMs. The reason is I want to take different actions in the Data Protecion Recovery Plan scripts production_vm_recovery and test_vm_recovery depending on which cluster the VMs failed over to.  Thanks,Howard

Disk Deletion Does Not Free Storage Space Immediately in Nutanix AOS

 Environment AOS Version: 6.8.8 Hypervisor: AHV 2022.10 CVM: Nutanix CVM version 5.18.3 VM Guest OS: Ubuntu 20.04 LTS Storage Type: vDisk attached as AHV data disk DescriptionWhen I create a new vDisk, write data to it, and then delete the vDisk in Prism, the underlying storage space is not reclaimed immediately. I still see the same physical usage reported in Prism Element and on the CVM filesystem, even after: Deleting all snapshots and clones Running fstrim -v /mountpoint inside the VM Executing the Reclaim Space action in Prism Triggering a manual Curator scan (curator_cli scan start) I expect the deleted blocks to be freed right away, but they remain allocated for hours or even days.Steps to Reproduce In Prism Element, create a new 50 GB vDisk and attach it to a running VM. Inside the VM, format and mount the vDisk: mkfs.ext4 /dev/nvme1n1mount /dev/nvme1n1 /mnt/testdisk Write 20 GB of test data copying from windows os disk Unmount and delete the vDisk in Prism.

Need help with NUTANIX server with ransomware incident

Hi. We have a Nutanix server with Qilin (AES-256/RSA-4096) ransomware incident. The server is compromised, so we extracted the physical disks apart. Someone can give details or links to reconstruct a virtual filesystem as a single raw ext3, ext4 or qcows2 filesystem to run autopsy or et. al. We have the tools, the experience, the equipment but we do not have the knowledge nor the tools to convert from ADFS distributed cloud filesystem to single volume / disk filesystem as extX, vmfs, LVM, … Nutanix server has 3 nodes, each node with 3 hard disks, so, it seems an RF=2 configuration. And please avoid suggestions as contact attackers, contact specialists, contact someone else, use the same server, use recoverit, recuva, testdisk ... We are the specialists and need help to deal with ADFS offline

Some virtual machines missing DNS settings post failover.

Hello Community I’m having an issue with some of my VMs post failover support has not been able to help me. We have a local cluster and a remote cluster. All of our VMs have static IP addresses. When I execute a failover the VMs receive new IPs as expected. 70% of the VMs will have the IP, Subnet Mask, Gateway and Primary/Secondary DNS populated for the IPV4 on the NIC.The other 30% will only have the IP, Subnet Mask and Gateway populated. The DNS settings are left empty. It is always the same VMs that have the issue. We have done a ton of troubleshooting so I can’t list everything that we have tried. Is anyone else having this same issue? If so, is the solution to just use custom scripts and deal with the issue?

Synchronous Replication with PC-Based DR

When configuring a protection policy for synchronous replication between two Nutanix on-premises availability zones (AZs) without utilizing a witness VM, under the Failure Detection Mode setting, in what scenarios should Manual Mode be used, and when is Automatic Mode recommended and that related to witness service?

Is it possible to deploy a Witness VM for Metro Availability at the disaster recovery (DR) site?

If I have two AHV clusters distributed across a primary site and a disaster recovery (DR) site, and I configure Metro Availability between them, is it possible to deploy the Witness VM at the DR site?

Difference Between Metro Availability and Sync Replication for Two AHV Clusters (Without Witness)

I have 2 AHV clusters (3 nodes), and if I want to configure synchronous replication between them, I have two options: Sync Replication and Metro Availability. I would like to understand the key differences between these two approaches and the specific features. Note that I will not use a Witness VM.

VM replications

Hello, I have a question about the functionality of VM replication between two clusters (Nutanix metro).I would like to know if my virtual machines defined on the main cluster can start identically on the backup cluster in the event of an incident. In fact, my question is more focused on the software and OS licenses that are implemented on the VMs. That is, are the licenses also replicated, or does it depend on the type of license?Best regards,

How to backup Prism Central\Element Configuration

I have seen a couple posts from 2017 and 2020 stating that the option to backup\restore the Prism Central\Element configuration is still in the pipeline. Is this option available now? If so, are there instructions online on how to do it?

Can Unplanned Failover Be Executed Without a Witness in Prism Central-Based DR Setup?

Hello Community, I'm exploring options for executing an Unplanned Failover in a Prism Central-based Disaster Recovery setup and would appreciate some insights. Our environment consists of two sites, each configured with its own Prism Central instance in an AZ-to-AZ architecture. Is it possible to successfully perform an Unplanned Failover without a Witness in this setup? If anyone has experience or best practices to share for handling failovers under these conditions, I’d be grateful for your advice! Thanks in advance!

Is there a way to access Recycle Bin to restore deleted VMs without contacting support

I accidentally deleted a few good VMs while cleaning up after migration from VMware to Nutanix, couldn’t find a straightforward way to restore them from recycle Bin just Like on a normal Computer, So the easiest way to was to re-migrate the VMs needed.If only i could just go to cluster recycle bin and do the restoration would save a lot of time!!

Cohesity Backup

Hello All,We have a Nutanix POC and I am playing around with the permissions. I am trying to create a role/category for our Cohesity backup. What entities are needed for the role. I assume cluster and VMs, but I am getting “Requested entity doesn’t exist” when trying to add the Nutanix source to Cohesity. It works fine when I add the source with a Prism Admin account. Can anyone point me to the proper permissions needed. TIA TJ

Azure Site Recovery

Has anyone completed an integration using Azure Site Recovery to protect a Nutanix VM and performed a test failure to Azure with a successful failback to on-prem?  I have seen a couple of blogs on treating the Nutanix VM as physical, etc.  Just wondering if this is being used to success out here in the wild and any knowledge you may have gained.  Thank you kindly.

Nutanix Disaster Recovery Options and Witness Configuration

Hi Team,We are considering deploying a Nutanix cluster environment to meet best practices while addressing our current demands. We plan to set up Site A as the production cluster and Site B as the disaster recovery cluster.Nutanix Disaster Recovery Solutions offer two options: Protection Domain-Based and Prism Central-Based, along with different replication modes such as Sync, NearSync, and Async.If we choose the Protection Domain-Based solution, for Sync (Metro Availability) we plan to deploy one cluster at each site (A and B), a VM witness in a VMware environment at Site C (which will be registered with Prism Element at each site), and a Prism Central at either Site A or Site B. The built-in continuous backup will protect Prism Central, and it will manage the Prism Elements of each site.If we opt for the Prism Central-Based solution, which offers more advanced features like protection policies and recovery plans, I understand that the witness is a service integrated with Prism Centra

metro availability and vmware

Is there a requirement to have ESX enterprise plus licenses in an nutanix metro availability with manual failover/startup in case of issues in 1 cluster?or will vmware standard licenses do? I don’t see the need for Ent+ licenses but had different feedback in the field. thanks!

Alternatives to AWS for Async DR

I’m currently backing up to AWS with AWS set up as Async DR site.  However, the price that AWS is charging has dramatically gone up.  Are there any alternatives to AWS?  I don’t need to run any VMs on the remote site, just a remote site to store my snap shots and the ability to restore easily. Thanks!

Magneto is in recovery mode after PC DR

Hi all,I received the following error when I tried to create a protection policy with sync replication for one vm from two clusters managed from the same PC, “Failed to apply protection policy 'PP_sync' on the VM 'CentOS7-DEV' because 'Magneto is in recovery mode after PC DR'”. Some time ago I restored the PC but I didn't find any error before now, also NCC didn't report any issue.Regards
