Maximum Capacity Event for nsx manager

Cambouch — Fri, 02 Jun 2023 15:08:50 GMT

Hello,

I noticed an alarm with severity critical that indicates that i have reached the max number of edge clusters.

I checked the monitoring dashboard report and that's what i find

Does this have any impact on the performance and need to be fixed ? should i resize the manager node ( i am now using small edge deployment).

Thanks in advance

Re: ScriptExecutionError While deploying tkgm cluster

The problem is resolved after adding DNS configuration on the Edge gateway. that way, every network created will use the DNS defined by the Edge. i defined 8.8.8.8 as primary dns and then it was able to resolve github.

ScriptExecutionError While deploying tkgm cluster

Cambouch — Fri, 20 Jan 2023 13:53:12 GMT

Hello,

I am facing a ScriptExecution Error while trying to deploy a tkgm cluster.

The deployment fails with a an error "unable to wait for post customization phase ". I tried to access the control plane VM "EPHEMERAL_TEMP_VM" to figure out the problem and i noticed that there are 4 services "Cloud-init,Cloud-init-local,cloud-final,cloud-config" that are not running as attached in the screenshot.

I am using CSE 4.0 for vCloud Director 10.4, TKG 1.4.3 and 1.5.4(Which are supported by cse 4.0) and Ubuntu as TKG OS no FIPS tempates downloaded from official product as required in the documentation.

I tried to modify manually the template and i successfully made all services running. Then, i tried to upload the template to my catalogue to use it as my TKG cluster template but it's not available among templates options.

So, the problem resides especially in the ubuntu template and i am not allowed to modify it to make all services running. Is there any workaround that i can try to solve this problem.

Thanks in advance.

Thank you for your collaboration dragance.
The problem was solved after reconfiguring the MTU between the Edge TEP and ESXi TEP and set it to 9000.

Yeah, i am talking about the static route that i defined on my tier-0 that routes traffic to my physical network.

Here is a brief summary of the configuration that i set following the official documentation.

Yes, i added a static route 0.0.0.0/0 that has 172.16.80.254(gateway) as next hop and enabled route advertisement in Tier-0 so it can reach underlying segments.

Hello Dragance,

Thank you for your interaction.

I am testing the IP from a machine that i attached under a tier-1 created under the same Tier-0 that contains my workload domain.

NSX-T Load Balancer is not working (Vsphere with Tanzu)

Cambouch — Thu, 15 Dec 2022 09:25:38 GMT

Hello,

I am enabling vsphere with Tanzu in my cluster. It creates automatically the load balancer on NSX-T side so no configuration is done manually, all set-up was done automatically.

For my environment, my workload domain is 10.244.0.0/21 , VIP network is 172.16.80.32/27.

The backend servers work normally and are accessible but the control node ip( 172.16.80.34) is not reachable although it's pingable and the specified port is open( i try telnet on it).

Any tips about what should i check?
