Nutanix CE - Failed AHV Update

Hi,

I recently created a new Nutanix CE, single node cluster to play around with.

Installation went fine, no issues

 

As per the Nutanix recomendation, post install, I ran Inventory (Updated LCM), then perfomed updates to NCC, Foundation and AOS, individually.

 

AOS went from 6.5.2 to 6.5.5.7 on the LTS Path via automated LCM updates.

 

I then Direct Uploaded the LCM Image for AOS 6.7.1.8 STS (lcm_nos_6.7.1.8.tar.gz) which successfully upgraded to 6.7.1.8 STS.

 

After running an Inventory, so LCM could find the latest supported version of AHV, the time came for the AHV Upgrade. Everything seemed to be going ok, until the reboot (after the AHV upgrade in progress screen).

 

Logging back on to the CVM and looking at the LCM page, I get the following error related to the AHV upgrade.

 

“Operation Failed. Reason: LCM failed performing action ahv_reimage_success_check in phase PostActions on ip address 192.168.*.* Failed with error 'Reimaging error: Unknown error, possible pre-mount failure?' Logs have been collected and are available to download at Log collected successfully on node 192.168.*.* at /home/nutanix/data/logbay/bundles/auto-lcm-log-collection-2024-06-13-50686382895.zip”

 

I was attempting to go from AHV 20220304.342 to 20230302.2024.

 

EDIT:

Running on:

Intel Core i7-8700
64GB RAM
Onboard NIC
Quadro P2000 (wanted to play with GPU, but don’t think that’s supported).
Toshiba NVMe 512GB - CVM
Samsung EVO 860 SSD 500GB (SATA) - Hypervisor
12TB WD HDD (SATA) - Data

 

Does anyone know the cause and resolution please?

Thanks

I’ll have to give this particular upgrade test in the lab, but AHV upgrades in CE can run into challenges, especially when there is a need to reimage.   This is due to that CE doesn’t follow the standard imaging workflow of using Foundation service to install the Hypervisor and instead uses a customized installer that leverages our Phoenix deployment tools directly.

Was there a specific reason you were going to that release of AHV?    If you want to DM me, I can share some contact details and you can send me the log file to take a look.

Thanks for your response, it’s appreciated. 

 

Thanks for the clarification on the AHV upgrade process on CE vs. Nutanix Production. Noted.

 

As I’m sure most are, we’re evaluating our VMware footprint, as we’re using Nutanix with ESXi.

After discussion with our Nutanix Systems Engineer, I’m utilising CE to better understand AHV, including the upgrade process. Whilst I know using CE isn’t ideal for this (HPOC), It gives me the flexibility to test on my own terms/time.

 

I’m just in the process of spinning up the CE Cluster in a virtualised environment to test (again), and hopefully give me the flexibility to rebuild/test a bit more dynamically.

 

If/when I get to the AHV upgrade issue again, I will be sure to contact you (thank you) with the log files.

 

Thanks again.

Upgrading AHV in CE is documented here: https://www.jeroentielen.nl/update-nutanix-community-edition-to-the-latest-versions-or-sts/

 

Keep in mind that this process is completely flawless in the normal commercial version.
