Things won’t always go to plan and the worst will happen. In this case, we lose 2 nodes from our 9 node rf2 cluster (e.g. one’s down for maintenance, someone forgets and reboots another node at the same time). Can someone point me at some documentation that outlines how we can recover from this and get the cluster back up and running. Is there any permanent fallout?Thanks.
Just a basic quick question I’d like confirmation on if possible. In a Nutanix Metro availability configuration (ESXi stretched cluster stretched across two sites) do all the CVM’S from both clusters have to be on the same Layer 2 Network to be supported?

I wanted to better understand syslog events for a given AOS cluster. It appears that a single node is designated as the ‘syslog leader’ and forwards all events to the destination collector. Thus, the remaining nodes send little to no events to the collector. Is this correct?My clusters run AOS version 5.15.4 LTS for what it’s worth.

It enables administrators to take inventory of the firmware and software in their Nutanix environment and perform updates in a simple, cluster-aware, fashion. LCM adds a management layer and logic that deploys firmware/software upgrades taking into account upgrade paths and potential conflicts between versions. LCM performs two operations: Inventory: Detects what can be managed on a cluster. Update: Performs an update to a certain version. With Release of LCM 2.3.2 we have introduced a new page which shows best practices guide and redirect you to FAQ’s troubleshoot guide it introduces two new FEAT’s along with several others AOS upgrade FEAT-10222 PC upgrade FEAT-10223 List of supported Firmware updates Nutanix (NX) Dell XC / XC Core Lenovo HX / HX Ready HPE DX Fujitsu XF Intel DCB HPE DL (G10) Inspur InMerge Please follow the links to check out additional information https://portal.nutanix.com/page/documents/details?tar

Hi,Looking to automate some reports using the Rest API. So far I can successfully pull out CPU, RAM and Physical & Logical storage cluster wide and snapshot details but am unable to calculate the values as shown on the capacity runway when viewing a cluster in PC.. specifically the storage usage figure for ‘snapshots’ and ‘system.Anyone know how these are calculated?Thanks
AHV hosts in cluster running AOS 5.18 or newer may become non-schedulable if bridge configuration across cluster nodes is not consistent. What is a non-schedulable node?A non-schedulable node is used to increase data storage on your Nutanix cluster and does not run any guest VMs on that node.To check if this situation exists on your cluster and to fix the issue, check KB-10217.
I need some help for understanding Prism Central Image Management. When I read Prism Central Guide (Limitations) I don’t understand “During the copy operation, cluster A becomes unavailable.”This comment in Prism Central Guide mean that can’t use “cluster A” Prism Element ?

We noticed that recently in our test cluster all operations take very long to complete. This seems to be due to long lasting “cerberus” tasks being executed with a type “uncharge”. Does anyone know what “cerberus” is doing or how I could speed it up? Whenever we kill the cerberus tasks manually all other queued ‘non cerberus’ tasks start to execute.
