Disk Deletion Does Not Free Storage Space Immediately in Nutanix AOS

Environment AOS Version: 6.8.8 Hypervisor: AHV 2022.10 CVM: Nutanix CVM version 5.18.3 VM Guest OS: Ubuntu 20.04 LTS Storage Type: vDisk attached as AHV data disk DescriptionWhen I create a new vDisk, write data to it, and then delete the vDisk in Prism, the underlying storage space is not reclaimed immediately. I still see the same physical usage reported in Prism Element and on the CVM filesystem, even after: Deleting all snapshots and clones Running fstrim -v /mountpoint inside the VM Executing the Reclaim Space action in Prism Triggering a manual Curator scan (curator_cli scan start) I expect the deleted blocks to be freed right away, but they remain allocated for hours or even days.Steps to Reproduce In Prism Element, create a new 50 GB vDisk and attach it to a running VM. Inside the VM, format and mount the vDisk: mkfs.ext4 /dev/nvme1n1mount /dev/nvme1n1 /mnt/testdisk Write 20 GB of test data copying from windows os disk Unmount and delete the vDisk in Prism.

Hello !!! Please help me! I found documentation from Nutanix stating that Docker is not supported on Win2016 using AHV, does anyone know of any more recent documentation that informs the version of Windows that is supported on AHV?Does Nutanix support Docker installation on a nested virtualization on AHV? (version 2024)

Help Shape the Future of NutanixWe’re running two short surveys — and your input would mean a lot! Search in Prism Central

Hello again from the research team! We’re trying to better understand how users interact with the 'search' option in Prism Cental, whether you use it, how you use it, and what you think of the search queries with operations. Your feedback will play a big role in helping us design a simpler, more unified search experience. Motion Design & IllustrationsWe’re exploring how visual elements like motion and illustrations can improve clarity, guidance, and overall experience in the product.You can take either survey or both (we’d love that! ). Each one just takes a few minutes, and your feedback helps guide what we build next.

Packer Windows 2022 Boot Loop

We are new to Nutanix coming over from vSphere and are experiencing the same issues that is discussed but not resolved on this thread:https://next.nutanix.com/ahv-virtualization-27/packer-press-any-key-to-boot-from-cd-dvd-issue-43213We are using Packer to build a Window 2022 image. We have customised the ISO to remove the "Press any key to boot..." prompt. However, we are now in a situation where Packer/AHV doesn't allow us to specify a boot order so the CD is constantly booting, installing and rebooting.We can continue the Packer build if we manually dismount the CD, however, we want to be in a position where this is a hands off build and orchestrated by a pipeline like our vSphere builds are.Has anyone managed to get around this?

Upgrade Prism Central

Hi everyone,I want to upgrade my Prism Central (current version: 2024.2) to a newer version, but I must have a plan to rollback, if something happens along the way. When upgrading using LCM everything seems straightforward and easy, when the checks are done and everything, but are there any risks/losses/possible damages? Can I go back to a previous version? Is there something specific to look out for? What to do if something breaks? Thanks in advance :)

V4 VMM API ERROR : PLAT-10006

Hello,I used the following GET request to list the VMs :/api/vmm/v4.0/ahv/config/vmsThe return error was PLAT-10006. I investiguated and found that only one VM was the culprit. When I use the previous endpoint with the name filter to pinpoint the VM I indeed get the same error.Finally, the following endpoint with the VM ext-id produces the same error :/api/vmm/v4.0/ahv/config/vms/${vm-ext-id}The same request in the V3 API produces no error. On the UI, the object is visible and looks normal. Even in NCLI the object is correctly fetched.I’m on pc.2024.3.1.1 and AOS 6.10.1.5Does any one know what could cause this ?Does someone know the full meaning of PLAT-10006 ?
