Hello, warriors of the digital ageCould you help a beginner in trouble? I took an internal snapshot yesterday to prepare for a problem moving nodes from an existing cluster to another cluster The previous one was done well, and the snapshot was about 1.8gb, but I found that even though I deleted the snapshot, I still had about 1tb of capacity leftI checked if the data was increased on another vm, but it didn't, so I think it's because of the snapshotErasing the snapshot doesn't reduce the capacity. What should I do?Where should I check first?AOS 5.20.3.5 / ESXI7.0 u2a

Hi, Im trying to understand how a Nutanix node works fine even if it’s connected to two switches not in stack. And i found that only one interface is enable when using the active-backup mode, but when im checking on the switches i fount that both interfaces are up. So, im asking if there is a way to check which interface is actif from AHV or CVM.

When a virtual machine is created and a name is given, this does not necessarily reflect the operating system’s computer name.  Is there a way via the Prism API v2 to get not only the name as define in Prism but also the name assigned to the OS?Neither of these return the OS computer name:/vms/vms/{uudi}The Nutanix Guest Tools are installed.Is it possible via the API v2 (or even via the API v3) to get the actual OS computer name?ThanksGary

I have a question about the new version NCC 4.X and AOS 5.20.X.When I upgraded the cluster from to AOS 5.20.2.1 from AOS 5.15. and NCC upgarde to 4.3.0.2. I found the the ping_hosts.INFO file in /home/nutanix/data/logs/sysstats has disappeared and I cannot check the latency between CVM every minute. There is only the ping_gateway.INFO file to check the latency between CVM and gateway. But there is also ncc alert that the inter_CVM_latency is high. So where can I check the detail latency information between CVM in the new verison?

I’m running Prism Central (PC) Scaleout version pc.2021.8.0.1 and when I select ‘Administration’. ‘LCM’ from the menu, I only get the following message;        Waiting for LCM Framework to start…Is LCM actually even a thing for PC?

Good day dearsI have 2 nutanix blocks, each 3 nodes , I have the following questions:I have vSphere license and I want to install it on the nodes, I only have prism element ( don`t have prism center) , should this work or I have to buy vCenter? While connecting the nodes to the same switch besides the firewall, should the switch be on access mode in order to Discover the nodes while using foundation, or I can segment the nodes through VLANS?

I want to Migrate AHV Cluster all VMs in to ESXi on Nutanix Cluster, can you please confirm which solution we used for further activity.

I get a firmware is not compatible with AHV version .The firmware version running on the nodes is Firmware revision :03.35 . When trying to install AOS on the nodes which I plan to add to my current cluster.Can i get a download  link for the compatible version of aos  with the firmware . The reason I ask this is that we are waiting for procurement to renew our support subscription which will take long and thus i cannot log a ticket . the nodes need to be re imaged.  I understand this is an older version of AHV .
