```
systemctl --failed
journalctl -u ignition-fetch
```
2. Ignition happens in a couple of steps
```
ignition -platform openstack -stage mount -log-to-stdout
```
then fetch
```
ignition --platform openstack -stage fetch -log-to-stdout
```
```
sudo journalctl -u kubelet
```
* Ignition file properties should has `/etc/hostname` , `/etc/resolv.conf`, `passwd` section with proper values.
### Ignition successful, CSR does not show

* If you see the error with `no such host` error in the `sudo journalctl -u kubelet` add the DNS service points to the right host/ip of the ignition IP.
* Using the IBM Cloud Internet Service or IBM Cloud DNS Service [link](https://cloud.ibm.com/internet-svcs/), add a new record to resolve the IP which points to domain.
* Reboot the worker node to flush the dns cache to resolve the DNS and CSR will appear for the approval. once CSR are approved worker will get added to cluster.
