Failed to deploy kubernetes cluster (Failed to deploy ntnx dvp)

Hi, No, you don’t need to configure them in your router, they are internal to Kubernetes. The reason of asking for them was to check you weren’t using the VM or K8s segment as pod or service ranges.  At this point I’d suggest you open a case with support, it’s going to be faster than trying to work out here what’s going on that is making your deployment to fail. Regards, Jose Ahh i see. So from the whole settings, my KBs should be deployed normally right? But something wrong that prevent it. Okay then, thank you @JoseNutanix i will open ticket then.

Failed to deploy kubernetes cluster (Failed to deploy ntnx dvp)

Hi @KarangDika  Can you share what IP subnets are you configuring for the pod and service networks? Hi Jose, I have 192.168.2.x segment for our current Guest VMs, CVMs and Hosts, PE and also PCI have 192.168.3.x segment for my KBs cluster with DHCP Enabled from PRISM. While the network pod i use default one from Prism Central that suggested meNet Provider : FlannelPod : 172.20.0.0/16Service : 172.19.0.0/16 I havent setup this network on my router and switch. Do i need to setup this network on my router first? Or i just change it into my current segment 2.x or 3.x? Sorry if there is a silly mistake that i did. Thank you.

I’ve set the Data Services IP like shown below. I take unused IP on that segment to be as Data Services IP.Data Services IPAnd when i deployed the kubernetes cluster, it failed but the workers vm, etcd vm and master vm has been created like shown belowKBs VMsAnd this is the iSCSI VGThis is the failure note when deploying KBs Cluster

Failed to deploy kubernetes cluster (Failed to deploy ntnx dvp)

Thank you for answering my question. So eventually i can’t deploy Kubernetes cluster right now since i dont have any external iscsi storage array outside from my nutanix cluster?

Failed to deploy kubernetes cluster (Failed to deploy ntnx dvp)

Yeah i know how to enable the Data Services. But what i want to ask is, what is this Data Services? Is it like an external storage array outside of my cluster? Like rubrick, Veeam, pure storage, etc? If that's the case, i wont be able to enable it since i dont have any. Or if its a VM that i need to create first inside the cluster, what is the detail of the vm?

Failed to deploy kubernetes cluster (Failed to deploy ntnx dvp)

Just adding some information, I just realized that when i want to deploy Karbon Cluster, i need to add the Data Services IP Address. How to enable it? Since i have no any external storage outside from my Cluster. I don't need external storage array to be added as a Data Services IP to my cluster?

My Cluster can't use the newly added VLAN

Hi KarangDika, just to be sure, which command did you use to create the new bridge? this hostssh "ovs-vsctl add-br br1" or this manage_ovs --bridge_name br1 create_single_bridge   if you used the first way remove the bridge and try with the second one Of course do a double check about ports and topology too I created from PRISM by adding new vs. And after i created from there, i checked using  manage_ovs show_uplinks and it shows up my bridge is already created like i did via PRISM. As i can see you are using “switchport mode access” for VLAN30 so why did you set the vlan tag 30 in the configuration? It should be native and you should use 0 instead of 30 i guess Let me know Hi @UPXI just realized i did give vlan tag 30 in configuration for ovs. Thank you for fixing my mistake.I just fixed it now and it can either the gateway or other guest vms.Thank you. Regards.VLAN Tag changed to native Guest VM can ping to gateway now

Hello, Sorry to hear about you difficulties. If you PuTTy to the HV/CVM can you ping from there? Are the vLan settings verified on the HV and CVM? Are the vLan setting verified on the switches? Good luck... Hi,I did test ping from CVM to my Guest VM with new VLAN, it didnt work.But when i try to direct connect my laptop to my switch with new VLAN, and ping the CVM, it worked.

Upgrading Memory in 1 node from 4 Node Cluster

Hi KarangDika, The DIMM configuration is unsupported. Either number of CPUs or the number of DIMMs, or capacity of the DIMMS are not supported. What is the node model? In terms of your account access raise this with your account manager — this is the quickest way. Alternatively, you can message me directly and I will do my best to help.   Hi, i just sent the details on message. Thanks for helping me.

NIC Usage on Nutanix Servers

    You are lucky, if you have GBICs you need only LC-LC FC patch cords that are really cheap. About the protocol you will use ethernet in both cases (1 or 10G), i guess you don’t need to care about that Yeah, thank you so much for the insight and solutions. And can i ask another question?Since you’ve mentioned that if i want to make physical segmentation network, it will make me lose redundancy right?So if i want to make another physical segmentation network, it would be best if i create another cluster on different segment and integrate them using prism central right?

NIC Usage on Nutanix Servers

If im not mistaken, there are already SFP+ plugged in the SFP+ port. So if we use the 1st option, we need to take out the original SFP+ from the node right? And for the 2nd option, actually we can use that since we have SFP+ 10G Finisar to be plugged in for juniper ex4600. Oh ya since you mentioning protocol, what is the best protocol for intra cluster network? Sorry for the question.

NIC Usage on Nutanix Servers

Dear @UPX ahh thank you so much for clearing things up.   Now im just have to look for a guide for configuring FCoE for SFP+ Nutanix towards Juniper EX4600.   Im so grateful that you can give me insight and clear things up for my newbie problem. Thank you so much. Since Nutanix is ​​dependent on standard GigE technology, there is no need to search for the FCoE configuration. You can configure your switch as you would for a normal network setup and treat the connections as simple ethernet ports. The Juniper configuration will likely be identical to the one you have on the Cisco Have a nice day! Yeah, i mean i need to look for configuring xe interfaces on juniper. But the kind of cable that nutanix used on SFP+ port is FCoE right?

NIC Usage on Nutanix Servers

Hi KarangDika, no question is silly. The rack fault tolerance is a really good choice. Replying to your questions: For intra cluster network, can we use only the eth port itself? Since for all this time, those 2 SFP+ Port was never being used since we have no idea what it is for and how to configure it. Is it for FCoE type or for 10Gig eth port?? Sorry, newbie on networking. you can for sure use only eth (1G Copper) but i suggest to use the SFP+. The SFP+ NIC is a normal ethernet NIC that give you the advantage of using 10G connection (10G is the best practice for production envirnoment) but, of course, you will need capable switches (10G) and all the GBICs/DACs needed for cabling. To be clear you can use: Patch cords RJ45 Cat5e/6 to cable 1G eth GBIC SFP+ and LC-LC fiber patch or DAC to cable 10G SFP+ ports  In both cases you can use the eth or the SFP+ the same way as NICs (for bonding purpose for example) but not in the same bond (never bond 1G with 10G

Hi @UPX adding my comment.  Are those 2 Eth port should have 10Gig speed? Or can we just use 1G speed and we use 2 SFP+ 10G port? If thats the case, which one will be the Guest VMs traffic? The 1G Eth port or 10G SFP+ FCoE port? Sorry for adding more questions. Just comes to my mind.

NIC Usage on Nutanix Servers

Hi KarangDika, the first question that comes to my mind is, just for my curiosity, why are you using NX 3060-G6 with only 2 nodes per block when you could have 4 nodes per block? Rack fault tolerance? About your network configuration: assuming you can cable all the nics, my suggestion is: for redundancy purpose use both 2 SFP+ per node on the first bond (usually br0-up) for intra cluster network (management, storage, zookeeper communications) (i would suggest LACP but dont know how to configure your two vendor switches, you could instead safely use and active-backup configuration) For guest vm traffic use both 2 eth per node configuring a separate bond (usually br1-up) with trunking (is the default for ahv but you have to check the switch side configuration) and allow there oll the VLAN tags you need Otherwise, If you cant connect all nics but only the eth i guess you have two choices the first (i suggest) you can connect and bond both eths, configure the trunk switch side, tag the ma

No Memory Usage in VM Table View

Hi @KarangDika  Memory usage is shown as "-" or "0%" on Nutanix cluster with AOS 5.1.1 or newer. Windows VMs are more susceptible to this issue.   To report guest VM memory usage, AOS relies on data provided by balloon driver, which is running inside the guest. This driver is part of the Nutanix VirtIO package. Linux VMs have this driver pre-installed in most of cases, but Windows does not have this driver packaged with OS. In case balloon driver is not installed or the installed driver version is old, memory usage will not be reported in Prism.   Please refer following article for more detail https://portal.nutanix.com/kb/000005671 Thanks, i forgot to install baloon driver in some of my VMs and now the memory usage detail is showing up again.
