Turning off deduplication
Hello,We used compression and deduplication for a while but now it is not necessary.I disabled these functions in the storage settings but the cluster is still showing the dedup space savings with no changes. This is after a week or so of turning dedupe off.I can’t find any documentation around disabling dedupe and what is required to ‘unoptimize’ the data.I’m using AOS 5:15.5.1 LTS and this is an old NX-1050 3 node system.TIA
Build new cluster vs. expand existing cluster
Hi All,We currently have an 1 Block, 3-node cluster (NX-1065-G5) with approximately 50 VMs on it. It is approaching end of life, and we are replacing it with another 1 Block, 3-node unit (NX-1065N-G8). At end-state all of the VMs will be on the new hardware, and the old hardware will be powered down.Would we be better to…Build the new unit as a brand new cluster, and move all the VMs to it using Nutanix Move. Expand the existing cluster by adding the new hardware to it, and then remove the old hardware from the cluster. Has anyone gone through either of these processes?Thank you for your suggestions.Marlon M.
Networking issues - trying to add in a second switch
Hi AllHavoc struck this morning when I tried to move my AHV cluster from old switch stack to new switch stack - the hosts, I think went into panic mode and started to restart various VMs.The background to this is: I have 2 x Dell X4012 core switches and 2 x Dell N3024 ToR switches, currently due to moving VMware environment to Nutanix only 1 x X4012 is connected to NIC 1 on each of the 3 hosts. From the X4012 there is a cross connect into the old VMware network Core blade switches (Dell 8024 x 2) which are connected to the old ToR N3048 switch stack, these are then connected to the router for VPLS and DMZ. So to move the connectivity, I thought I could add the second NICs of the hosts to the second X4012 and disconect the crossconnect and the first NICs thus using the newer switches, albeit on the opposite NICs. I planned to reconfigure and update the first X4012 and add back into the stack with a LAG to the N3024 stack and no crossconnect. I moved the NIC connections and lost all
NGT Tools install with Ansible
I’m developing Ansible playbooks to deploy Linux and WIndows servers from disk images and using cloud-init (already working) and sysprep (forthcoming, I’m not a Windows specialist)The NGT Tools are pre-installed in images.The problem is that new VMs show NGT : “Not Installed” in Prism.Is there something else to do ?Thx
What's the performance impact if we change RF from 2 to 3?
Dears:We have a 3 node pure NVME SSD clusters with RF 2. Now we plan to expand more 5 nodes and change the RF from 2 to 3. We have a little worried about the performance on :(1). During conversion phase from 2 copies to 3 copies.(2). For BAU usage, if RF3 performance will slower than RF2 because every write need do 3 times compared of 2 times. I got the question 1 answer from Nutanix Resiliency – Part 2 – Converting from RF2 to RF3 | CloudXC (joshodgers.com) and want to see any more experience. For question 2, any experiences could be shared? Thank you very much! P.S. We have enabled compression feature.
How configure vLAN native on vLAN10?
Hello everyone,I have to install the first Nutanix cluster from a customer but I can't figure out how to setup the network.All customer switches (Aruba 2930, 2920) have the native vLAN (vLan1) dedicated to workstations and servers, while the management network is vLan ID 10 where the ESX, storage controllers, backup NAS and the Veeam server backing up the current infrastructure.This is the situation of all my customers, vLAN10 is completely isolated and unreachable from the native vLAN1, this was done to prevent any ransomware from affecting the backups as well.Now, Nutanix recommends configuring the CVM and hypervisor host VLAN as the native, or untagged, VLAN on the connected switch ports.I'm sure it would be nice to have all of the management in the native, adding a node would be much easier and I think the simpler things are kept the better.Furthermore, vLAN10 is propagated on many remote racks because obviously the backup NAS do not reside in the same racks as the servers, how can
Nutanix CE install failing
I have a used NX-3060-G5, with 4 nodesI am trying to install the new CE 2.0 on itEach node is configured with the e5-2650v4 x24x32 sticks of ramBMC version 3.94BIOS Version G4G5t8.0They all have the same 64gb statadoma 512GB SSD and a 1TB HDDI had used nodes a and b as test nodes orginally, then i tried to reinstall the new CE 2.0 on them and i keep getting failures at 2402/2430 hypervisor installation in progress with the read out to please take a look at the installer_vm_*.log inside foundation logs to debug hypervisor installation, then it restarts the install process and repeats. 2 of the nodes this installed on just fine, but they were not a reinstall of CE, they had vmware running on them previously.I have tried installing the latest supermicro bios and get the same issue, i have screenshots of the logs that i could find. Not sure if i can post them on here. Just seeing if anyone may be able to assist or point me in the right direction to find out why this keeps failing when al
Accounts for security scans
Hi, I’m new to Nutanix, coming from the vSphere world.I am working on getting our new Nutanix infrastructure set up to run Qualys scans for security. I have been looking at the following document:https://portal.nutanix.com/page/documents/kbs/details?targetId=kA07V000000LXYqSAOI am getting stuck at determining which accounts to use to set up authentication, so that Qualys can run its scans on the Hypervisors, CVMs, and Prism Central appliances. My research shows that adding new accounts via the OS to these components is not supported. Does that mean that Qualys then has to log in as root, nutanix, and admin respectively, to scan these components? Or am I looking in the wrong place for the Qualys account to be set up, to scan for vulnerabilities and compliance? I feel like I'm missing something here. Thanks!
Expanding Cluster with LACP
Hi allI have a cluster with vswitch active - activeI have new nodes to expand and I did theses steps below 1 - root@ahv# ./network_configuration to configure ips and vlan tag2 - Configure lacp 2.1 ssh email@example.com "ovs-vsctl set port br0-up other_config:lacp-time=fast" 2.2 ssh ovs-vsctl set port br0-up other_config:lacp-fallback-ab=true 2.3 ssh firstname.lastname@example.org "ovs-vsctl set port br0-up lacp=active" nutanix@CVM$ ssh 2.4 ssh ssh email@example.com "ovs-vsctl set port br0-up bond_mode=balance-tcp"3 - Expand cluster The nodes were joined success in the cluster, but when I checked the vswitch configuration of theses nodes was changed to active - backupDid I do something wrong? What better way? Thank you
How to restart a hypervisor upgrade after aborting
Can someone let me know how I restart the upgrade on the failed host? I cannot seem to find any restart/retry button.The host failed to go into maintenance mode and now upgrade says aborted on this one host.I have fixed the cause of maintenance mode now so it will be fine.

Can't install NX G6 AOS 5.10 version?
The NX G6 demo equipment is currently updated with the latest firmware. If you try to install version 5.10 to test the AOS upgrade with the latest version of the foundation, the 4. foundation version will not mount, and the 5. latest foundation version will not configure CVM after rebooting after installation and installation will fail. Is it like this originally?

Can't install the lower version of AOS?
There are still many places where the old version is being used.Even if you try to install it with the previous version (AOS 5.10 or lower version) of the foundation on the G6 device to test the upgrade, it cannot be installed.Is it because all the firmware is up to date? It was the version that was originally installed. AOS 5.10 versions are not installed now?In foundation the log is "Device 2 :The Length of Name is not correct" The phrase continues to print. Please reply from those with experience.

Replacing upcoming EOL hardware process
My 3 node cluster consiting of 1065-G5 nodes is coming EOL this year. I will be replacing the hardware with a NX-3360N-G8 cluster. What is the recommended workflow for replacing the hardware? One thing to note is the current cluster is licensed with Prism Pro and the new one will be licensed with Starter as I’m not using all the features in Prism Pro.Is the replacement as easy as expanding the cluster one node at a time, migrating the workloads and then removing the old cluster? Will there be any hiccups with difference in licensing?
Foundation IP not set.
Hey guysI am reinstalling three Lenovo HX5521 nodes and I got stuck on the below errorFoundation IP not set. Try running the “set_foundation_ip_address” script on the desktopI'm running the foundation vm on the same subnet of the IPMI interfaces connected directly to an unmanaged switch, without VLANs or any other configuration. connectivity is perfect. I already reviewed all the settings and tried to reimage foundation using ESXi and AHV. Both result in the same error.Im running;Foundation_VM-5.2.2 AOS euphrates-5.20.3 LTS VMware-ESXi-7.0.1 or AHV-20201105.2244I've been trying to solve this problem for three days now, but so far I haven't found any clues. Any help will be greatly appreciated. Thanks! 👷🏽
Running Reapir Host boot disk hung
Using phoenix to reimage a node after a failed satadom, after phoenix is loaded, I uploaded AHV ISO so it can proceed to install AHV/AOS. It turns out I uploaded the lcm_ahv_el7.nutanix.20201105.2267.tar.gz instead of the AHV-DVD-x86_64-el7.nutanix.20201105.2267.iso. The install is now hung at 75% Node discovery succeeded. I have tried to install the proper iso, but it immediately failed at that same progress. How can I cancel this install so I can try again?I did find this error in the foundation log. It looks like the error happens if you use the html 5 client to mount the phoenix iso, but I am using the java client.

Cannot put node back to cluster after removal
Hello eveyone,following my last post I eventually got my C node to be alive. (it was not booting nor being visible whatever I tries, always down).I can ping it with both IPv4 and IPv6 addresses, connect to it in SSH, run commands etc.Now my situation is : while I was struggling with my node down, I removed it from the cluster with Prism. I think I could bring it back after… But it does not work.As you can see here, the C node (#3) is now missing :I use the “Expand cluster” tools in Prism Element, I add the node manually, it is detectedI check the mode, validate and it starts to expand.But after a few minutes I get the error :Failure in pre expand-cluster tests. Errors: Failed to get HCI node info using discovery It seems like the cluster refuse to consider the node as “free”, or the node itself refuse to join because it thinks that it is still in the cluster.Thank you very much for any help you could provide

Adding disks to storagepool on CVM
Hi all, I’m wondering if someone can help me out with the first install of a nutanix CE single cluster with esxiThe installation went fine but, and followed this link to make it work. https://vmik.net/2021/01/26/nutanix-ce-install-esxi-2021/I see that only have 1 disk in the storagepool. Is there a way to add a disk into the CVM? or do I have to mount it first. can someone help me out? many thanks.
