Hi everyone, I've got a simple question. I already tried to change it in the config yaml files (via the gui or via cli) and searched all across the internet. But i can't figure out how to change the hostname of a Harvester node. Thanks in advance!

Are there any plans to support encrypted volumes for workloads in harvester? I know longhorn supports them, and it's something that could be useful from a SOC2 compliance standpoint. 🤔

How we can change Harvester VIP IP after installation of cluster ?

@here: We need to implement the the version management for VM images. Just checking what tool and process you guys are using to store VM images (I.e. git…etc)

Importing qcow2 question. I have a 150GB qcow2 image converted from vmdk . When I import it using file i get “Context Canceled” error after 99% of uploading. Using URL i see the error “Pod spec node ID host3 doesn’t match the desired node ID host3" after 99%. How do I debug what is wrong?

Does anyone have any advice on trying to migrate a vm from Harvester 1.0.3 cluster -> 1.1.0 cluster? i tried backing up a vm from 1.0.3 and adding the same backup store to the 1.1.0 cluster, and it doesnt show up. also tried creating a vm with the same name, and that didnt seem to make the backup show on the new cluster eiether.

figured i'd try here before posting a question.

Does anybody know of a Harvester speed comparison compared to other persistent storage options?

Hi everyone, trying to install harvester v1.1.0. When the host name is entered, pressing any key is to return to the previous page. What is the reason for this?

I'm pretty sure that my single harvester node is not using the second nvme disk and everything is using one. via the UI storage is showing the default disk is not ready and that the UUID does not match. when I select add disk it shows me nvme0n1 but then a format option (which I am not prepared to do unless I know it is not truly using that disk. rancher@harvester:~> lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 3G 1 loop / sda 8:0 0 476.9G 0 disk ├─sda1 8:1 0 64M 0 part ├─sda2 8:2 0 50M 0 part /oem ├─sda3 8:3 0 15G 0 part /run/initramfs/cos-state ├─sda4 8:4 0 8G 0 part ├─sda5 8:5 0 80G 0 part /usr/local └─sda6 8:6 0 373.8G 0 part /var/lib/harvester/defaultdisk nvme0n1 259:0 0 476.9G 0 disk I have never really been a *nix engineer but through years of supporting infrastructure equipment based on *nix and having to get in to the guts of things (EMC, vmware, f5) I have picked up on a few things. How do I determine whether nvme0n1 is not sda?

lspci is not installable and the harvester RO filesystem and the list PCI devices in the UI is experimental and enabled but I can't see anything via that.

maybe I'm going about this the wrong way. I have a second nvme disk in my single harvester node that I would like to use for my VMs. What is the proper way AFTER installation to use this disk?

@tall-school-18125 I'm not sure if you are also affiliated with harvester documentation or the UI but it seems the 1.1 documentation is not up to date regarding multi disk management, at least in the screen shots. https://docs.harvesterhci.io/v1.1/host/

perhaps a different approach might help me, can anyone point me to good write up on adding an additional disk on a harvester node. The official documentation is not even accurate for multi disk management (https://docs.harvesterhci.io/v1.1/host/) and that is even before I should be able to specify a new storage class in settings where the parameters of existing storage classes do not appear, nor does that tab/iframe/element have any fields in creating a new storage class. I'm thinking some adventurous community member's tutorial or blog post might help.

Hi Everyone, We have a harvester node with the following resources

Allocated CPU: 96C
Allocated Memory: 188GiB
Allocated Storage: 758GiB

Now when we are trying to create VMs (

CPU: 4cores

Memory: 8Gi

)on the node using our custom k8s controller (operator), we observed that

Actual memory usage was close to 35%, but the reserved memory on the Harvester node was almost 99% and VM creation was not going through anymore.

(attached snippet). Can anyone explain me the reason for this and how can we overcome this ?

Which Harvester versions does Rancher v2.7.0 support?

Running into two problems on Harvester. We have Harvester running in the lab connected to Rancher 2.6.9. It works fine. We started out with early versions of both and have upgraded to Harvester 1.1.0 and Rancher 2.6.9. Everything works fine. We’ve since tried to add a new Harvester cluster in our DataCenter, while Harvester can be accessed through rancher, we can’t spin up new clusters. We’ve tried reinstalling Harvester, and various other tests. We also tried installing a fresh Rancher 2.6.6, and then connecting the new Harvester cluster to it and it worked. We then upgraded to 2.6.9 and it also worked. We even tried upgrading to 2.7.0 and it also worked. We then installed a fresh 2.6.9 and it did not work. So there is something from 2.6.6 that is left behind in the install that allows Harvester to work. Any help/guidance is greatly appreciated. We have also commented on the following bug in Rancher as it describes the full effect. https://github.com/rancher/rancher/issues/38863

Hello, we have connected Rancher 2.6.9 with the Harvester cluster v1.1.0. While trying to deploy RKE1 cluster it's waiting with the message "Waiting for ssh connection..." and after a while, this node is replaced with another and the cycle repeats. The issue looks similar to: https://github.com/harvester/harvester/issues/1519. Is there a fix/workaround?

@Team: Any idea what is the use of the "vip-pools" under "settings" ?

Just a heads up-- It was not straightforward to get here. On the page https://harvesterhci.io/ the link "Join our Slack Community" https://rancher-users.slack.com/archives/C01GKHKAG0K does not take you to requesting an invite. (I found myself spinning in circles for a while.) I finally found a link to request an invite (yay) after installing Harvester on it's splash/home page which pointed me to https://slack.rancher.io.

Hey team, I'm testing a cluster deployment and get "NotReady" for the cluster after a fresh install. Looking at

kubectl -n harvester-system get po

I see

kube-vip-s9hsl

with Status

Error

and disk read massive (230MBps). How can I dig into why this system isn't coming up?

FWIW the 2 NICs are on the same network. Should those be seperate?

The node is the Master, btw

I restarted and am still getting massive disk IO but different pods are now in Error states:

harvester...

= CrashLoopBackoff,

kubevirt...

= StartError with a second in

ContainerCreating

Longhorn question. On harvester nodes, do we add muitlple disks by “Add Disk” or do we add a Raided single disk?

Team: Do we have any production ready harvester-go-client which we can use to create Virtual Machines from my Go Code?

After a fresh install of 1.1.0 (yesterday and today), I get: Failed to pull image "rancher/harvester-cluster-repo:v1.1.0": rpc error: code = Unknown desc = failed to pull and unpack image "docker.io/rancher/harvester-cluster-repo:v1.1.0": failed to resolve reference "docker.io/rancher/harvester-cluster-repo:v1.1.0": pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed (in the cluster dashboard events explorer)

Hello team, Can't find any information on the internet what is the biggest server cluster that Harvester now manage. I have a more that 100 servers, most 16/32 with 64GB RAM, more that 30 of them with GPU, and now thinking to move to harvester HCI. But the question is who using that for more than 100 servers or at least 50... Can find any information on the internet.

Team: I have a two node cluster. My primary (First) Node went down. However, the secondary node is not picking-up and showing "Not ready" in console. Is this a limitation of harvester? Isn’t a single point of failure? Any suggestion on where to look into logs? Looks like a complete down?

Question: I have harvester installed on a server which also creates longhorn persistent storage on that server. If I now create a bunch of VMs for a downstream rancher cluster and the application I deploy on that cluster needs persistent storage. Is there a way to point the cluster to the longhorn storage created by Harvester?
