Describe the bug

coredns can't start:

 [WARNING] plugin/kubernetes: Kubernetes API connection failure: Get "https://10.43.0.1:443/version": dial tcp 10.43.0.1:443: connect: no route to host

To Reproduce

upgraded from a previous working version

maybe on a new install it will also reproduce...
Expected behavior

Logs

Additional context

Maybe related to this:
k3s-io/k3s#7013
but this https://docs.k3s.io/advanced#old-iptables-versions
did not help or I did not manage to apply....

The text was updated successfully, but these errors were encountered:

jimmykarily · 2023-06-21T12:06:32Z

I tried a fresh install:

qemu
kairos-opensuse-leap-v2.2.1-k3sv1.26.4+k3s1.iso
config.yaml

#cloud-config

k3s:
  enabled: true

users:
- name: kairos
  passwd: kairos

kairos-agent manual-install --device auto config.yaml

and it works as expected. coredns Pod comes up just fine. No errors are reported in journalctl -f -u k3s
There is a warning printed in the coredns pod but it doesn't seem to break anything:

[WARNING] No files matching import glob pattern: /etc/coredns/custom/*.server

I can try an upgrade. @Ognian which version did you upgrade from?

jimmykarily · 2023-06-21T12:55:19Z

10.43.0.1 is where the kubernetes api service should be running. No route to host means it can't be reached. Either it's not running at all or something is blocking access to it. @Ognian if you have ssh access to the box, try to run sudo journalctl -u k3s and check for errors. Try to run k9s as root as well to see if you can access the kubernetes cluster in general.

Ognian · 2023-06-21T13:06:19Z

@jimmykarily k9s is working, this is where I have the info about coredns from; sudo journalctl -f -u k3s shows a lot of errors, I noticed that i.e. this one:

Jun 21 13:02:07 lp3dnode k3s[1544]: E0621 13:02:07.627507    1544 kubelet_node_status.go:701] "Failed to set some node status fields" err="failed to validate nodeIP: node IP: \"192.168.6.64\" not found in the host's network interfaces" node="lp3dnode"
Jun 21 13:02:07 lp3dnode k3s[1544]: time="2023-06-21T13:02:07Z" level=info msg="Connecting to proxy" url="wss://192.168.6.64:6443/v1-k3s/connect"

is trying to connect to 192.168.6.64 BUT ip ashows that 192.168.6.54 is the correct ip...
May be I should delete /usr/local/.kairos/lease and reboot?

Ognian · 2023-06-21T13:08:10Z

@jimmykarily Ups there is no /usr/local/.kairos/lease
and I was upgrading, actually from 1.6 to 2.0, 2.1, 2.2.1 if I remember correctly...

Ognian · 2023-06-21T13:22:47Z

so there is a wrong ip the internal ip is 192.168.6.54 and not 64 How can this be changed?

jimmykarily · 2023-06-21T13:34:06Z

The IP address change may be related to this: #1381 which got fixed and then got fixed again.

If that's the problem then either you wait until today's release is out (which has the fix) or you try to change the IP address manually to what it was (I see some options here but I'm not sure how to do that on a read-only OS: k3s-io/k3s#5787). Also, the fix is based on us storing the machine-id so that we can restore it. I'm not sure if upgrading to this version will find the old machine-id stored. @Itxaka since you implemented the fix, do you think it's going to work? Probably the broken versions should be skipped (so that the IP address doesn't change with the reboots).

Another thing, is it needed that all upgrades are applied? Can't @Ognian just upgrade from 1.6 to the latest in one step?

jimmykarily · 2023-06-21T13:35:48Z

Also, if this is indeed the issue, we should add it to the release notes (e.g. which versions to skip to avoid this problem). I assume, for those who used static IP addresses, it's not a problem.

It should be possible I think. The original machine-id should still be under /usr/local/etc/machine-id so @Ognian make sure to save it somewhere.

Then once upgraded to the fixed version, it should auto pick teh exiting machine-id and save it under /etc/machine-id which should give you the fixed IP back...I think.

But after upgrade, for sure it wont change again.

If a fixed IP is required it also should be possible to skip dhcp and set it manually via https://kairos.io/docs/advanced/networking/#static-ip meanwhile

Ognian · 2023-06-23T18:05:57Z

this did not work. I had to do a reset...
Now there is again a problem with the rpi version, where there is no network...
I know you are working very hard on this, but somehow for me the last working version was 1.6.1 ...

Ognian · 2023-06-25T11:13:25Z

I did some additional test today:
somehow after 2 -3 reboots there was a network again so that I could access it via ssh...
somehow it is stuck here:

sudo journalctl -fu kairos-agent

any ideas?

jimmykarily · 2023-06-26T08:35:15Z

@Ognian these logs don't seem to be the cause of the problem. There just say that edgevpn is working fine. When you say "there is no network" I assume you mean you can't SSH. This could be cause by various problems not related to networking. E.g. even a syntax error in the cloud config could break SSH (because user accounts won't be created).

Eventually you SSHed to the machine so I assume it worked.

Regarding the original problem, does k3s now start? Does it use the correct IP address? If you can also attach the output of sudo journalctl -u k3s and sudo journalctl -u kairos-agent it might help (without -f, so that we see all the logs).

Ognian · 2023-06-26T10:34:43Z

@jimmykarily sorry for not being precise enough. When I say "there is no network" I mean the rpi does not have an ip address (on finishing boot you display the kairos in ascii art and below eth0: and wlan0: and the corresponding IP is printed). In my case the IP address is NOT displayed. I think that the network stack is simply not started...

So what I wanted to say is that only after 3 reboots I was able to get an IP and than ssh into the machine was without any problem.

Here are the logs:

sudo journalctl -u k3s
-- No entries --

 sudo journalctl -u kairos-agent

sudo journalctl -u k3s-agent
sudo systemctl status k3s-agent
sudo systemctl status

I would say that the state partition is no more expanded after first boot (#1448)
What do you think?

jimmykarily · 2023-06-26T14:19:08Z

I could be. I can't tell which partition is which in kairos from the output above (This command will make it clearer lsblk --list /dev/disk/by-path/* -o NAME,PKNAME,PATH,FSTYPE,MOUNTPOINT,SIZE,RO,LABEL).

I think the only partition that would automatically get expanded would be COS_PERSISTENT, the last one. But I see /dev/sda4 in your output being the last partition and only 64M in size, which doesn't look like it expanded to me.

You probably hit the bug you linked but I'm not 100% sure that this is the only problem you are facing. That bug has a fix which I'm trying to test here: https://github.com/kairos-io/kairos/pull/1497/files but I'm facing CI issues since last week and haven't been able to verify it's ok to merge. Stay tuned.

Yes, /var/lib/rancher is mounted no COS_PERSISTENT and that one isn't expanded thus it runs our of disk. #1448 is the issue you are facing. Until this is fixed and released, you can try the workaround at the description of that issue. Just use kairos-agent run-stage instead of elemental run-stage which is now deprecated.

The original issue (#1531) was fixed and will be part of the next release. Let's track #1448 separately. Closing this one.
