Why? I constantly get low space errors for /home

Hi AllIf the system can recognise that the space is low, why can it not be programmed to do its own housekeeping and clean up?  I find it irritating and time consuming doing something that should be automated.  Or am I missing something?  Has someone already created a script or process to fix this? Thanks in advanceEric

Complete newbie not sure how to get to the config screen

Hi all the expert,I’m completely new to Nutanix.I tried to install the Nutanix Community Edition onto my existing rack mounted HPE ProLiant DL380 Gen9 server, so I followed this YouTube video, but it’s definitely outdated, since the links shown on the video are different to the download links available from the post from 3 years ago (created on 29th September 2020) So I have downloaded the installer ISO (version ce/2023.03.01/phoenix-ce2.0-fraser-6.5.2-stable-fnd-5.3.4-x86_64.iso) and nothing else, since the other download links are for Windows, but my purpose is to install Nutanix itself onto the host directly to replace ESXi completely, so I thought the VirtIO for Windows ISO and AHV Plugin (.msi files) are not really applicable in my case.So it get stuck at the getting files screen for a long time, and then it errored out as the screenshot at the bottom, then a root login line showed up, I can’t even get to the grey screen to select the hypervisor and configure the IP like on the Ge

Adding Storage and Nodes

I have expanded the existing block by adding two 1065-G8 nodes, each equipped with three HDDs and two SSDs. However, the new nodes, along with the HDDs and SSDs, are not being recognized, and there appears to be no power supplied to them. I am currently seeking Nutanix documentation on hardware installation but have not found relevant information yet. any idea?

Using Ansible to run nuclei commands

We have an issue with backup snapshots getting stuck on our cluster, and of the many ways we use to find these, one of them is running the command:nuclei vm_recovery_point.listI was hoping to start down the path of automating the discovery of these recovery points using Ansible.  However when we run the nuclei command via Ansible, we get this error:            "E0724 14:10:07.661153Z   15562 jwt.go:82] ZK session is nil",            "2023/07/24 10:10:07 Failed to connect to the server: websocket.Dial ws://127.0.0.1:9444/icli: bad status: 403"I think this means that nuclei calls the localhost websocket on the CVM, but Ansible interprets that as a call to the server I’m running ansible from (ie the ‘controller’ server), and not the CVM I’m remotely connected to.Does anyone have any advice on how to handle this?  I’ve also looked at API calls, but can’t find any that give me the same info.

Clarification on new CE Install, drive layout

Hello All,I am installing Nutanix on a four node cluster. Each cluster has three HDDs, 1 NVMe SSD and 1 SATADOM for the OS. I was intending for the SSD to be my hot tier and the HDD to serve as the cold tier.When installing I see that it’s required for the CVM to be assigned to a disk. This seems to indicate that I will likely need to add an additional drive to the layout to dedicate to the CVM or does the CVM storage double as the cache tier? I do have an additional spot for a second SATADOM that I could use for the CVM storage however I cannot find any guidance on its required size.Thanks in advance!https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Community-Edition-Getting-Started-v2_0:top-sysreqs-ce-r.htmlStorage devices, Cold Tier 500 GB or greater available Maximum 18 TB (3 x 6 TB HDDs) Hard disk drive (HDD) or solid-state drive (SSD) for cold-tier storage Note: Ensure that the drives are attached to the node through a Host Bus Adapter.

LCM Dark Site issues on Windows server

I have installed IIS on Windows servers, performed LCM framework in 2 phases for version 2.7 and after that was able to set LCM to use Dark site and to point to my IIS web server http;//MyIP/release. That allowed my to run inventory. However I can’t update any other component. I have downloaded LCM packages for AOS, foundation, FLOW, etc extracted with proper WinZip version or embedded tar. Have correct folders structure as per LCM Dark Site guide, but still LCM do not see any component for upgrade. What else I can do?And for sure for example my AOS and AHV requires update. Permissions checked, MIME types checked. CVMs and PC can talk to web server. Compatibility bundle has been extracted and copied to root folder /release. Don’t know what else might be the problem. Most likely something silly. Please help. And just FYI, direct upload to PE is not an option for me. I have many clusters in DarkSite and need to use web server as a repository.

Removing failed node Error: Cannot mark node for removal. Node xx (xx.xx.xx.xx) is to be added back to metadata store

So I was wondering what Akbor actually did here.  In the reply he says he just, “This is now resolved, I used edit-zeus to set state.”Is there a set of instructions or some sort of helpful advice for what he meant by edit-zeus?  I tried poking around but it seemed pretty dangerous for a linux noob like myself LoL Thanks for any help you can give,                                                        Brian  Removing failed node 2 months ago 1 reply 52 views Hi everyone,We had an issue with SATADOM on of the nodes, which has been replaced.  Unfortunately, we had to rebuild the CVM as well as they hypervisor and now need to add the rebuilt node back to the cluster.  The problem is we can’t remove the existing node as we are getting the following error:Error: Cannot mark node for removal.

All licenses reset before clean re-allocation on two production clusters

Hi Guys,Can anyone confirm that it is possible to unlicense one or two NX clusters that are in production in order to re-allocate the same licenses but smarter?Explanation: We have 2 clusters with 3 AOS Pro licenses sets (Cores + FLASH)Set1: first 3 nodes of cluster1 (2019, renewed 2022)Set2: first 3 nodes of cluster2 (2021, renewed 2024)Set3: 2 more nodes, one for each cluster (2022)We should then have set1 allocated for cluster1, set2 for cluster2 and set3 split between the 2 clusters but currently each set is used partially in cluster1 and 2 which is a mess for next licenses renewal…So my target would be to reclaim all the licenses for both clusters and then reallocate them, cleaner,  through seamless licencing. Is that scenario possible without stopping the exploitation? Thanks for your advice and guidance.

Certificate errors in fresh installation

Hi again.So i did my fresh installation, and at long last the password worked.Now, i can access the https://ip-of-cvm:9440, but only using “Internet Explorer”Any other browser will say something like this:“IP” usually uses encryption to protect your information. This time when Microsoft Edge tried to connect to “IP“, the site returned unusual and incorrect credentials. This can happen when a hacker tries to impersonate “IP” or a Wi-Fi login screen has disconnected. Your information is still safe because Microsoft Edge disconnected before any data was exchanged.You can't visit “IP” right now because the site has sent encrypted credentials that Microsoft Edge can't process. Network failures and attacks are usually temporary, so this page will probably work again later. And using “Internet Explorer” it seems like a lot of virual elements arent displayed correctly.

UEFI VMs encounter random "inaccessible boot device" BSOD issue

Just wondering if anyone knows if there are any documented instances of someone being able to successfully re-inject the VirtIO drivers into a UEFI-based Windows VM?  At first, we thought it was just a VMware problem, but then we had the same issue happen on a native-AHV VM.  The VM operates normally for weeks, with regular reboots, but randomly after a reboot, it bluescreens with an "Inaccessible Boot Device" error.We haven't found a single "solution" that has actually fixed the problem.  We can get the VM to boot into recovery mode, but none of the recovery options work.  If we manually load up VirtIO driver from the command prompt (drvload vioscsi.inf) we can regain access to our drives, but adding the driver to the boot image via DISM does not help (dism /image:c:\ /add-driver /driver:vioscsi.inf).  The server reboots to the same blue screen.SFC doesn't help, neither do the standard bootrec options (i.e. bootrec /fixmbr, bootrec /fixboot, bootrec /rebuildbcd), nor does "bootsec /nt
