asked in AHV Virtualization

Installation

Hi @TrouBle You need to create VLANs on your cluster First. Do the following:Click on the gear placed top right corner on Prism ElementThen on the left menu go to Network section and click on Network ConfigurationYou’ll se a window like this (but without vlans of course)Then click on Create Subnet and fill in your network detailsThe last step will be to create a vNIC on your VM and you’ll be good to go Hope this helps Regards!

Nutanix AHV VM disk accidentially deleted ...

Hi @Didi7 Nutanix has a “Recycle Bin” Prism 6.5 - Recycle Bin (nutanix.com) which retains deleted VMs and volume group vDisks for up to 24 hours. If you are on a commercial version contact Nutanix Support. Hope this helps! Regards!

Hi @ZAnton I’ve deployed successfully Microservices Infrastructure with CE. Don’t know if it’s “officially” supported but it works.I was getting errors with PC 2022.6.0.10 but afterwards tried with PC 2022.6.0.9 and it worked. Hope this helps Regards!

asked in AHV Virtualization

Installation

Hi there guys! I asked for the AHV installation in a USB drive because I ran into a similar issue last week. I’m currently using an NX-1065-G5 node as a single node cluster. 1 SSD for CVM and 2 HDDs for data. Boot drive used to be a SATA-DOM and with it, LCM updates worked flawlessly, but, because of wear and tear it died eventually. As a work around I started using an USB drive for AHV install (yes, it’s not supported) but update through LCM ended with the host booting into dracut. Something like this To solve the issue I’ve followed this great article form @Jeroen Tielen which saved the day and now my single node cluster is updated, up and running! Hope this helps Regards!

Installation

Hi @TrouBle Regarding to NTP servers not reachable, maybe it’s related no DNS resolution but if you are running LCM, prechecks have been passed and they are reachable. Do you have AHV installed on an usb drive? Regards!

Installation

Hi @TrouBle From the CVM you can use ncli cluster-get-name-servers to check which one are configured (if any)You can add them with ncli cluster add-to-name-servers servers=”The Server” one by one (up to three)Hope this helpsRegards!

How configure vLAN native on vLAN10?

Hi @Purlilium That is. You can configure Nutanix switch ports with VLAN 10 as native and the rest of VLANs in the trunk. Or you can filter what VLANs will be on the trunk. It’s up to you. If you need to connect VMs to VLAN 10 you can create the network on Prism Element with tag 0 because is the native vlan. Afterwards you can create all the networks in the trunk on Prism Element with their respective tag. Hope this helps Regards!

How configure vLAN native on vLAN10?

Hi @Purlilium As @JeroenTielen wrote having AHV and CVM on port's native VLAN is to keep things simple. I'm not an expert on Aruba switches but i've found this article https://www.arubanetworks.com/techdocs/AOS-CX/10.07/HTML/5200-7867/Content/Chp_vlans/vlan_cmds/vla-tru-nat.htm which talks about changing the native VLAN of a port. Based on your first post you have 2 VLANs:VLAN 1 (WKS and Servers) = Configured by default on all switch ports as a native VLAN VLAN 10 (ESX,...) = The VLAN that you would like to configure as native VLAN for Nutanix nodes With that being said, I would configure VLAN 10 as native on required ports, which means that anything that you connect on that ports will be on that VLAN without further configuration, and the other required VLANs as trunked. Then on your cluster via Prism Element create a new network for VLAN 1 to connect required VMs. Hope this helps Regards

Nutanix CE install failing

Hi @Brandonperkinss Maybe the sata-doms on your failing nodes are wearing out. It’s possible for you to test that nodes with another sata-dom and check if the install works? Hope this helps Regards!

asked in How It works

SnapShot Deleted but Have a Large Capacity

Hi @junsu I think it’s related to curator scans. Please check this article https://portal.nutanix.com/page/documents/kbs/details?targetId=kA03200000098CQCAYHere’s an extract:Description:After removing or deleting many large files or VMs, free space on the Nutanix cluster appears to not increase or takes a few hours before the free space is seen/reclaimed. The service responsible for cleaning up space, Curator, takes time to perform scans on the cluster and spreads the storage across the disks and carefully removes the correct files (egroups) while maintaining redundancy for any data you want to keep.It takes a few Curator scans before all expected free space is available again. To remove more data, it will take longer time for Curator to clean up data relative to the existing workload of the cluster. In case after 36 hours, space is not reclaimed and does not appear as free space, consider engaging Nutanix Support Hope this helps Regards!

Do you have to use both NICS and SFP ports in a NX-6035-G4

Hi @bravoj Saw your post on reddit, I’ll be answering here.I assume that the diagram that you drew can be close to this one below. Am I right?I assume that you have a pair of SG550-16 10 Gig SFP+ “Stacked” “Linked” or whatever fancy name the technology has and also you have a pair of Base-T Core Switches running at Gig. How are your virtual switches configured? (Active-Backup, Balance-Slb or Balance-TCP) By default CVM’s use VS0 and they have to run at 10Gig for the storage replication to other nodes. This will be you VS0 connected to the SG550-16 switches. Regarding to your diagram you should also have a VS1 configured Connected to core switches for the UVM traffic. At this point your storage replica and management traffic is flowing through SG550-16 at 10 Gig and your VMs are connecting to “external” world through Core Switches at 1 Gig. I had a customer with the same configuration running for a long time because he wanted to split the UVM traffic from the CVMs and he also had G4’s (

AOS and Prism Relation

Hi @MMASLOUH This is covered on Nutanix Hybrid Cloud Fundamentals course (Modules 1 and 2), which can be taken online via Nutanix University. Please take a look as soon as you can (It helps a lot on getting a wide view of Nutanix platform). HCI consists of two main components:Distributed Plane: The distributed plane runs across a cluster of nodes delivering storage, virtualization, and networking services for guest applications, whether they are VMs or container-based apps. Management Plane: The management plane lets you easily administer HCI resources from one place and one view and eliminates the need for separate management solutions for servers, storage networks, storage, and virtualization. Prism: Is the management plane that provides a unified management interface that can generate actionable insights for optimizing virtualization, provides infrastructure management and everyday operations. It gives Nutanix administrators an easy way to manage and operate their end-to-end virtua
