Network connectivity failure scenario

Hi folks, I want to ask about the details regarding the network connectvity failure and cluster behaviour in such cases. I am mentioning two such scenarios but other scenarios may also be possible. Scenario 1. If one host in the cluster gets completely disconnected from other nodes at network level but host is up and running what will be the cluster behavior and what will happen to the vms running on that particuar host Scenario 2. If all hosts in the cluster get disconnected from each other at network level but hosts and cvms are up and running, what will happen to the vms running on each host.

Mixed Hypervisor in same cluster ?

Hello, with latest AOS (5.10 or newer) it's possible to run multiple hypervisor in same cluster ? For example one cluster with 5 nodes with esxi and 3 nodes with AHV ? Thanks Manuel

Space really available in a container with thick provisioned VM

Hi all, we are performing a POC and we have a cluster that originallly had about 30 Tib of available space made of SSD+ HDD. Then, to show the customer the performance improvement moving to All Flash we made an inline conversion addind SSD and removing all the HDD and now we have a total available space is about 11 TiB. The storage container has compression enable and the real used capacity is 4,5 Tib. The problem is that most of the VM are thick provisioned and the actual use space is reported at 12 Tib hence above the available capacity. This triggers RED alarms on the Prism console saying that he Data Resiliency is not available. So I have 2 questions: 1) since the actual used capacity is 4,5 Tib what happens in case of a disk failure? 2) how can we manage to eliminate these alarms? Question number 2) is particularly relevant since if we succeed in the POC and the customer could purchase Nutanix all flash systems , they will like to use th

Prism Central monkey always happy

I just upgraded our Prism Central to version 5.7.1 and noticed that the widget with the banana-holding monkey never changes when we get an alert from one of our managed clusters. I removed and re-added the widget from the PC console but it still never updates when we receive an new alert. Grated, this is not very important but has anyone else seen this issue?

Is there a network status for Nutanix?

URLs such as insights.nutanix.com *.compute-*.amazonaws.com release-api.nutanix.com ... According to our security team, those URLs are white listed, so they must be down. e.g. "release-api.nutanix.com could not be reached. Please check Name Server and Proxy settings" Thx

HyperV 2012 R2 Migration to AHV

Hi, We have a Windows 2012R2 HyperV host with about 8 Windows 2008R2 VMs. These VMs are Gen1 using .vhdx as the file system. I'm currently running Ntnx 4.7.4 and was wondering the following: Does the image service import .vhdx files or do I need to use qemu-image ? If I use something like Starwind V2V converter, it supports QCOW2 and RAW, is there a preferred Ntnx format ? (Image inserted below) Does the SMB version on the CVM have unique specifications ? I was trying to use Storagecraft Shadowprotect Recovery options (Linux based) but it would see the UNC?Thanks in Advance, G [img]https://uploads-us-west-2.insided.com/nutanix-us/attachment/2506iD6764FB6092E7F6F.png[/img]

DELETE cluster/nfs_whitelist/{name:.+}

I have been trying to remove an existing nfs whitelisted machine through Rest API explorer. API: cluster/nfs_whitelist/{name:.+} I have tried giving the path parameter with different combination of IP/sunbnet mask but all were failed with error message: Specified NFS Whitelist does not exist. Here, machine IP is whitelisted as I can see it in Filesystem whitelists but I am not able to figure out the exact representation of path parameter. If anyone knows, then please tell me.

Hello, I'm struggling with the installation of AFS on the last CE - reading 20180425.199 on Prism Element. After several tries (3.2.0, 2.2.3, 2.2.0 and 2.2.1) all failing with the same annoying message (Software is not compatible with the current installed NOS version), I finally call for help. Does anyone know which AFS version is compatible with CE 2018.04.25 ? Luc.

Nutanix operating in a 'private' cluster (feature workarounds)

Hello, In setting up Nutanix we do not allow it on the Internet. How much does this constrain what we can do with it? ie Life Cycle Management (LCM) Although LCM allows us to point to a different source we will still need to get the Modules somehow? Although LCM lets us start an Inventory it still seems to want to go out and get a Manifest file and then it fails? Can these be downloaded somehow? Where else are we going to find difficulty with? Thank you...

AHV Replication Options

We are designing a Nutainx cluster utilizing a NX-1065-G5 four host block licensed with Prism Pro and Acropolis Ultimate. This will be the production site managing approximately 12 workloads. For the recover site we are looking at building a 3 host Dell cluster. The hypervisor throughout the environment will be AHV. There will be a Cisco metro network solution between these two sites. My question is, what are our options for replication between the two sites? The KB lists solutions for ESXi and Hyper-V, but does not mention AHV configurations. Is this because this is a native solution built into the Prism solution? Thank you for any enlightenment.

Zeus configuration cache is not created; try again later

When trying to use the allssh "manage_ovs ...." I get the above error. As I understand it Zeus and Zookeeper are close friends(as one would expect). Zookeeper implements the cluster configuration information while Zeus is used by other cluster components to access it? Somewhere I read that when you manually add a new node to a cluster Zookeeper on that new node is not active? Any information would be appreciated (even rabbit holes). thx.

Is AF node also using cluster cold pool & clarifications on ILM thresold

Hello, I have questions on SSD pool and ILM mechanism I still did not found answers for after cross reading dozens of web sites and forums. Probably the response is obvious but I feel like I am missing something here and would like to have certainties on these points. So, let's suppose I have a 4 hybrid (1065) node cluster and I am running out of SSD. Q1) Can I technically add an All Flash node in the same cluster container ? Q2) Will the VMs hosted on this specific AF node automatically be all flash VMs (with no ILM and cold tier drain mechanism) ... or will they use the cluster cold storage pool (from other hybrid nodes) ? ===== Regarding the ILM mechanism and different SSD thresold, I (think I) understood that: - data will preferentially be stored on local SSD of each node until it reaches 75% usage - If one node reaches 75% of SSD usage, then ILM will send "less hotest" local SSD data over the network to other remote SSD nodes - If all nodes fi

Storage Containers - business purposes for many - or is that a bad thing?

Hi All I have read that a single storage container is all that should be used as Nutanix takes care of all the functionality like de-dupe and ssd allocation. I started my Nutanix journey with a number of containers for dividing into business parts eg: Production SQL, Production Web, Dev, and Test. Is this division a sensible way to go or do the latest versions of Nutanix negate that? I intend to limit dev and test to slower drives in the pool, is that possible outside a container approach? Many thanks E.

Network switch best practice

I have 8 port 10BaseT 10g switch and I have four nodes with dual 10g and dual 1g. I also have a 1g switch with 50 ports. If I plug all 8 10g nic into the 10g switch I will not have an uplink port. However I still have thx 8 1g nic. So this leaves me with a couple options, and I was curios what best practice would be. A few options I have consider are: Only use one of the two 10g ports per node. Configure AHV to use 10g for I/O only and 1g for connecting to the outside world. *not sure if this even doable*

Networking with Dell Switches: VLANs and NICs

Hi All Is anybody else just going round and round in circles with Nutanix and the network it resides on? I am getting soooo peeeeeee'd off!! The man at the show said easy peasy, 15 minutes to deploy, which 15 minutes? The last 15 in 2019? Dell supplied, but don't really know the product so they pass calls off to Nutanix who do their bit (very well, no complaint there) but then hand the things about Dell back to Dell, so I am not getting a joined up answer. So the crux is that I don't have a stable network and I am ready to rip it all out and go back to VMware. Unfortunately my budget has gone and I have to rely on Communities for answers - not a lot forthcoming. Is anyone else having these sort of problems or is it just me?

New to Nutanix - pointers please...?

Hi All I am having my first foray into Nutanix using 3 x Dell XC servers and 2 x Dell X4012 switches (stacked), TOR switches are Dell N3024 stacked - I have come from a background of VMware using blades and SANs, so I a little confused on the process for setting up the external networking. What vlans etc do I need on the switches for the Nutanix management, vmotion and storage etc? Is there any best practice documents or has someone completed a similar task and documented the procedures? Any hints, tips or configs gratefully received. Thanks Eric

OVS Networking - Unable to bridge eth0-4 for other networks - Error

What's my goal? Right. I have 3 networks that cannot talk to each other for "reasons". Mostly because we have a test system that utilizes the same IP addresses (ORACLE Reasons) and we test & demo software in Prod, Demo, & Test networks. I just did a foundation on my system because I did an upgrade and the networking customization I had to do with OVS changed and wouldn't work anymore. Now that I'm working on a new install, I'm having trouble configuring the network and getting issues I didn't have before. I've created and recreated several times using different varieties of below commands and still same outcome. Some commands below are from various tries, but same result.

Prism and DVS Iissue

I have encountered an issue while migrating to a dvs, I am running esxi 6.5 on a 3 node cluster. The setup is new so there are no VMs apart from the CVMs and a test VM on the host. The dvs already exists and I am doing one node at a time and as such I added one of the NICs from node A to the dvs. I then did a quick test with the test VM on each port group I have configured to confirm connectivity. I then attempted to migrate the VM Network port group created on vSwitch0 that the CVM on node A was connected to, the migration "worked" but connectivity to the CVM was lost. In addition to losing connectivity to the CVM on node A, I am now unable to access prism from any of the CVMs or cluster IP. The page loads but once I attempt to login nothing happens. I even powered off node A in hopes that I can get to prism but still no luck. All CVMs and the cluster IP are reachable via IP, the esxi hosts for node B and C are also fine and reachable.
