Red Hat Bugzilla – Bug 1304149
Unable to recover from certain bad values.
Last modified: 2016-09-13 12:25:52 EDT
Description of problem:
During hackathon we ran across an instance of a user entering bad values in fusor-installer, subsequent runs with correct values were not honored and machine was broken.
Steps to Reproduce:
1. Use an ISO install of RHCI
2. Enter the correct IP address, say 192.168.155.10
3. Enter all other IP related values incorrect as 188.8.131.52,
ensure ALL other entries are wrong, unsure which one causes the problem, set all to incorrect values.
4. Proceed with install and see NTP warning
5. Attempt to fix errors and enter 192.168.155.1 and other correct values for the environment.
See that the issue is not fixed and still broken.
The only additional information to add is that when you re-run fusor_installer and fix all the bad IP related values (with the exception of the IP Address which is correct) it will still report an NTP connectivity warning.
It never actually uses the new IP Address information that you just entered or restarts the networking on the system.
IP Settings used to reproduce:
3. IP address: 192.168.155.10
4. Hostname: sat61fusor.example.com
5. Network mask: 255.255.255.0
6. Network address: 184.108.40.206
7. Host gateway: 192.168.155.1
8. DHCP range start[[BR]]: 220.127.116.11
9. DHCP range end: 18.104.22.168
10. DHCP Gateway: 22.214.171.124
11. DNS forwarder: 126.96.36.199
14. NTP sync host: clock.redhat.com
This is because the DNS forwarder address is bad. We may want to add a forwarder check as we did for NTP to ensure that they entered a valid DNS server. It will be impossible to check until after networking is set up though.
Can you please re-test this. I'm having trouble getting stuck and reproducing this. It's possible with all the changes it's no longer possible.
If you can reproduce it can you please provide steps for input that gets you there?
