Clicked Enable button for Karbon—what’d I just do?

So I was starting to read about Karbon kubernetes management in Prism Central, inadvertently clicked the Enable button, and now something's happened/installed but it’s unclear what.Can I uninstall or disable it?Can it even run on ESXi? (It would appear not to be the case)

Multiple worker node pools in Karbon

Node sizes are set when creating a kubernetes cluster in Karbon. These sizes cannot be changed once the cluster has been built. While this is fine, it would be nice if it was possible to have several worker node pools with different node sizes in a cluster, like in AKS (https://docs.microsoft.com/en-us/azure/aks/use-multiple-node-pools). As of now , we need to create several clusters to have worker nodes of different sizes, and this adds more master and etcd nodes as well as the need for a new subnet.For example, we could create a node pool for applications with high memory needs and another for applications that need more CPU in the same cluster. Then, we could specify which named pool we wanted to deploy to.With storage, we already have the option to create several kinds of storage, fast, slow, object, and so on.

Failed to deploy kubernetes cluster (Failed to deploy ntnx dvp)

Hi,I’m trying to explore kubernetes by deploying Development Cluster. But it only stuck at 8% and eventually failed with notification (Internal Error : Failed to deploy ntnx dvp).Here is my detailSegment 192.168.2.x for Guest VM,PC,AOS and AHV. Segment 192.168.3.x for Kubernetes cluster itself (DHCP Enabled)Each segment can ping each other and all those segments are able to access the internet.Here is the detail of the temporary deployed Karbon VM (After failed deploying, the VM got deleted automatically)I’ve been reading someone posted same problem like mine, and it solved because of the VM previously unable to access the internet. But mine is able to access internet, PC and the Internal Nutanix.Perhaps someone can enlighten me what did i do wrong?-Able to pull newest docker image-Able to ping Prism Central (192.168.2.11)-Able to ping CVM (192.168.2.2)-Able to access internetDeploying Cluster stuck at 8%Deleting VM after failure deploymentNotification Internal Error : Failed to deploy

Veeam Backup Chain Break after Nutanix VM failover and back

I’m new to Nutanix and we are using Prism Pro to move a VM from one 6.7 Vmware farm to another and back again. That works 100% but Veeam V11 can not see the VM once it is moved. It’s like the UUID is wrong but I have checked that and it is ok (same) Support are looking into this and are saying this is a unique case… surely this must be common? If there is no solution we will end up with the same VM added to the Veeam backup job, again and again… I have tried using TAGS and direct add to veeam…

Sybase ASE on AHV?

Hello Everyone,Has anyone here run Sybase ASE in a Linux VM in AHV?   We have a few legacy physical servers that I’m looking to migrate into our AHV cluster.  I know it ‘should’ work but looking for a reference or reassurance from anyone who has ‘been there, done that’.  Thanks,Jim

Minimum Permissions Required for Karbon kubectl Access?

I need to create a role that will be able to get the 24 hour certificate to be able to run `kubectl` calls against Karbon.When I look at the role creation page, there are a lot of options there.  I am a bit overwhelmed in trying to figure out what permissions I need to just grant this one function.What permissions are needed for a user to be able to get the 24 hour certificate to be able to run `kubectl` commands?

Commvault with Nutanix - Best Practices Checklist

Use a Nutanix cluster external Data Services IP address when using IntelliSnap. Install a VSA on every Nutanix compute node. Install the MediaAgent software on all the VSA proxies. Install CommServe and MediaAgent on a secondary Nutanix cluster to separate backup and production infrastructure to protect against failure. Follow Commvault sizing guidelines. Create a virtual server client proxy group for easier management. When using IntelliSnap, colocate the MediaAgent software with the VSA. With ESXi, when you add ESX hosts to vCenter, make sure that the format of the ESX host name matches the host name format in vCenter. For example: If the host name format is short name, use short name to add the host to vCenter. If the host name format is FQDN, use FQDN to add the host to vCenter. If the host name is an IP address, use the same IP address to add the host to vCenter. With ESXi, use NBD as the transport mode whenever possible. With ESXi, configure the management network interfaces t

Self Service VM Customization

I want to introduce Self-Service VM operations via Prism Central for our end-users (do not have CALM). So, I’ve used cloud-init (Linux VMs) and cloudbase-init (Windows VMs) along with customization code (Python) to deliver this Self-Service VM provisioning experience. You may refer https://github.com/cybergavin/nutanix/tree/master/self-service for details of this set up. Any feedback always welcome. Sorry if the code isn’t too pythonic as I’m a python newbie.

Nutanix CVM - diskspd

I’m new to Nutanix and we have a Nutanix cluster online. For testing purposes I’m running diskspd test in a VM.I’m running some diskspd test with identical VM configs in several enviroments 3-tier Hyper-V/ VMware and HCI Nutanix AHV.Why is it that running a test with -Sh flag (no software/hardware cache) gives almost 10 times lower results in Nutanix compared to other platforms? Without -Sh flag Nutanix is running test with higher results compared to my other testing platforms. Is it because of how CVM is designed to work? I’m just trying to understand.

Determining appropriate methodology for cpu over subscription

We are new to Nutanix. We are migrating from ESXi to AHV.  We currently have some level of CPU oversubscription in place on ESXi.  We anticipate the need to oversubscribe CPU on some clusters and I am looking for ways to do this safely.  I’ve looked in the Best practices guide but there was very little there.  Any help would be appreciated.

Data protection Migration and failback

Hi, I’m new on the Data protection feature. I’ve done the a test VM migration to another nutanix cluster. The thing is after the migration, the VM on the source will be destroyed. I’m planning to use the Data protection to migrate the VM from the source cluster to the target cluster. I would need to failback the VM to the source VM. Am I able to restore the VM on the source site?

Nutanix replication or recovery with volume group

Hi Everyone,I want to know what nutanix version can do replication or leap recovery plan with volume group (iscsi)? I currently use the CE version for testing ,my Nutanix CE and PC version are NUTANIX 20190916.276.I'm testing the iSCSI space of volume group mounted on Windows Server,then execute the plan of leap failure. However, after my windows server fails to DR, there is no iSCSI space on the windows server, and I do not see that the volume group is sync to DR.Is there a problem with my configuration, or is the CE version not supported at present?Has anyone ever done this test?Thanks.

Keycloack operator/PotgresSQL permission denied

Hello everyone,  I'm having some trouble using the keycloak operator installing on a simple Kubernetes Cluster on Karbon Basically, what happens is that when I install a new Keycloak, the PostgresSQL is not able to run properly because it does not have permissions to create a new directory on /var/lib/pgsql/data/userdata As far as I understood, the problem is related to the securityContext which is not set to the postgres deployment even if Postgres runs always using user 26 (as can be noted here: https://catalog.redhat.com/software/containers/rhscl/postgresql-10-rhel7/5aa63541ac3db95f196086f1?container-tabs=dockerfile) I had to do a lot of workarounds to make it work, and finally I succeded by configuring manually the security context as follows: securityContext:  fsGroup: 26  runAsUser: 26 There is any possibility to set the security context via the operator? if not, can you please point me out what is the correct solution to apply?

Nutanix Disaster Recovery Solutions

Nutanix offers a variety of DR solutions. The flowchart provides a detailed representation of disaster recovery solutions.  Leap with two Prism Centrals: Asynchronous replication: it enables you to protect your data with an RPO of 1 hour or beyond.The policy creates a recovery point of the VMs in every 1 hour (or in the hourly time interval that you specify in the RPO) and replicates it to the recovery site NearSync replication: It enables you to protect your data with an RPO of as low as 1 minute.The policy creates a recovery point of the VMs in minutes (1–15 minutes) and replicates it to the recovery site. You can configure disaster recovery with NearSync replication between two AHV or ESXi clusters at the same or different on-prem sites Synchronous replication: It enables you to protect your data with a zero recovery point objective (0 RPO).You can configure a protection policy with Synchronous replication by defining the VMs or VM categories that replicate all the writes on the pro
