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. Node xx (xx.xx.xx.xx) is to be added back to metadata storeDoes anyone know how we can overcome this error?P.S. we don’t have Nutanix support coverage anymore.Many thanks in advance.Akbor

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
