I haven’t upgraded to v1.0.3 yet because I’m away from my three node cluster and have no way to remotely manage the hosts, but with v1.0.2 I’m finding Longhorn and Harvester quite fragile. On several occasions I’ve had the issue with too many shapshots. At the moment I have one VM which I just cannot start, seemingly because Longhorn is in a loop attaching and detaching a volume every 5 seconds. And I have another volume which keeps failing the replica on node 1 and rebuilding it, then failing the replica on node 2 and rebuilding it, then failing the replica on node 1 again and rebuilding it, then failing the replica on node 3 again and rebuilding it. I’m a little scared to upgrade Harvester in case the situation gets worse.

I installed harvester instead of esxi7, it works fine but I have a problem with the network. The server is in a network made like this: 192.168.136.0/24. harvester was installed on the ip: 192.168.136.231. With esxi the network was the same 1923.168.136.0/24, while when I use harvester each VM uses 10.52.0.0/24. How do I create a Network that works with the same subnet where harvester is installed (192.1686.136.0/24)?

Anyone have a good idea how to change the management IP of a node?

I have a Ubuntu 20.04 server VM running on a Harvester node, which I am using to process large files. when I run
sha256sum my-file
It starts incrementing buff/cache memory, until it uses up 100% of free memory and causes the machine to reboot. If I continually clear the page cash using
echo 1 > /proc/sys/vm/drop_caches
then I am able to prevent reboot.

Is there anyway to change the VM configuration to fix this issues?

Hello, I’ve been away from this for a bit, but just installed Harvester 1.0.3 on a Sandybridge based system. I’m getting some weird kernel errors:

Copy code

Aug 28 20:20:28 localhost kernel: mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 5: cc18cf0000010093
Aug 28 20:20:28 localhost kernel: mce: [Hardware Error]: TSC 0 ADDR 107d4a0c0 MISC 21400c0c86
Aug 28 20:20:28 localhost kernel: mce: [Hardware Error]: PROCESSOR 0:206d7 TIME 1661718020 SOCKET 0 APIC 0 microcode 71a

I wasn’t able to install 1.0.3 from a flashdrive or ISO. I had to install 1.0.2 and then update. I’ve also noticed VM performance is terrible. I’ve tried deploying Rancher clusters to my Harvester box, but they never finish deploying and keep running into random errors. Sometimes a node will successfully go online, but it won’t stay online and will go back into provisioning.

is there a way to force a node to try to reprovision?

Is there an Intel processor generation requirement that should be listed in addition to the core minimum requirements? For instance, Haswell and newer?

Running into an issue with registering my Harvester server to Rancher. I rebuilt my Rancher server, and replaced the registration URL in Harvester with the new URL from the new Rancher server. Harvester isn’t registering to Rancher, and it’s been nearly 30 minutes since I updated the URL. I’m on Harvester 1.0.3. Is there anything that I need to do differently to register to a new Rancher server after being registered on a previous server?

Harvester v1.0.2 to v1.0.3 upgrade. It's been hung at the Phase 3: Upgrade system services phase for 14 hours, logging every 5 seconds that it's still waiting in the

ErrApplied

state, as seen in the logs of the pod running the upgrade job - as found using the command in that trouble-shooting page. Unfortunately that troubleshooting section does not say what to do to remediate any issues at this stage. I'm thinking, kill the pod and see what happens...?

Hello, I need to be able to add storage LUNs presented to harvester nodes via Fiber Channel Qlogic HBA card. I can see the LUNs on OS level using "cat /proc/partitions", however I don't see them when I try to add disks. Appreciate help getting them added. Thanks

Hi gurus. Question, I do not seem to find a documentation on how I come about adding a new disk or volume to the default disk on my Harvester node. I think I was a little to quick when installing so I likely chose to use the installer disk for both installation and vm-data 😞 Any tips on how I can put it right without reinstalling my 3 nodes?

Team, how to create multiple admin users in Harvester? I have checked the “Account & Api” link, but it is not giving any option to add new Admin users? Any input please?

Might be worth the try - go in the vm config - advanced options - show more - and change the value for "Reserved Memory" to 256 or 512.

Hi everyone, trying to install harvester v1.1.0 RC1 just for testing new version and in fetching configuration yaml i `m getting: Unsupported Harvester Scheme Version 0, please use new config and refer https://docs.harvesterhci.io/v1.1/install/harvester-configuration/, but link for v1.1 is not working. I have yaml from v1.0.3, but seems there are some changes in v1.1.0. Do you have some preview of new configuration yaml file?

Hi Mark, it looks like a resource issue in the Longhorn layer so the VM is paused while the volume is degraded. How many nodes do you have? Have you been able to see any relevant message in the longhorn manager log?

I tried to create a network with terraform, the "harvester_network" resource, for a DHCP-network, so route_mode=auto. When harvester gets the CIDR and Gateway of the network, then terraform fails since it tries to apply those values for route_cidr. So I get "can not use route_mode auto when route_cidr has been specified", but my terraform resource has no route_cidr present, and otherwise no changes since creating the network. Does anyone know how to get terraform to not send route_cidr on updates of the network?

Hi All 👋 - Quick question - by default is there a firewall that needs to be setup on the Harvester nodes in order to get port 80 and 443 access?
