Reinstall of CoreOS after adding disk bombs
by Shivaram Mysore 04 Oct '19

04 Oct '19

Hello, I used mmcblk0 as the initial boot disk and was able to get coreos installed and fully operational. I then added a disk sda. I reinstalled (via PXE - fully wipe) coreos on mmcblk0 Generating "/run/initramfs/rdsosreport.txt" Entering emergency mode. Exit the shell to continue. Type "journalctl" to view system logs. You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot after mounting them and attach it to a bug report. possible culprit segment: (attached full report) 0m] Started dracut initqueue hook.

Questions on FCOS Internals
by John Osborne 25 Sep '19

25 Sep '19

Hi SMEs, Iv'e been using Fedora CoreOS (FCOS) and I had some questions. Any help would be greatly appreciated, thank you! Q: Is there a way to pass FCOS an ignition file while it's running for the next reboot? Or do you need to externally kill the machine and pass the .ign file again through the firmware? Q: Can you see the ignition file while the machine is running that was passed during startup? Is it unmounted somewhere or in the initramfs.img file? Q: It looks like I can turn on automatic updates on FCOS by editing /etc/rpm-ostreed.conf. Will that make my machine auto-reboot? When? Q: How do rpm-ostree and ignition work together? Does rpm-ostree pull down ostree updates on some sort of cronjob type schedule? Are the updates in an OCI image (oscontainer)? Where is the image unpacked? How does ignition know which image to use when it starts the machine? -- John Osborne CHIEF openshift architect, RHCE Red Hat Public Sector <https://www.redhat.com> josborne(a)redhat.com M: 7037721090 <https://red.ht/sig>

Network configuration issues
by Shivaram Mysore 19 Sep '19

19 Sep '19

Hello, I have a box with multiple network interfaces. I am running: # *uname -a* Linux rhino 5.2.11-200.fc30.x86_64 #1 SMP Thu Aug 29 12:43:20 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux # *cat /etc/*release* Fedora release 30 (Thirty) NAME=Fedora VERSION="30.20190905.0 (CoreOS preview)" ID=fedora VERSION_ID=30 VERSION_CODENAME="" PLATFORM_ID="platform:f30" PRETTY_NAME="Fedora 30.20190905.0 (CoreOS preview)" I am happy with eth0 as it uses DHCP. What is the best way to configure on the system the below command: $ *sudo ifconfig eth1 0* I have a container in which I have an interface - call it a OVS bridge which will be linked to eth1 and that interface will get the IP address. I also need to force the container to use eth1 as the default route interface and not eth0. I understand that Network Manager (/var/run/NetworkManager/) is the method to configure networking on this CoreOS. Is this model supported? Any references to how this can be accomplished? I have another similar use case for a VPN tunnel. Appreciate pointers. Thanks & Regards /Shivaram

Re: EC2 access for testing?
by Geoffrey Marr 19 Sep '19

19 Sep '19

I have been using Amazon's "Free Tier" cloud machines to test EC2 images since 2016. Anyone with an Amazon account (which is free) can spin up a "free tier" machine to run the tests on. With access so easy, is it Fedora's job to provide users/testers with an account with which to test these images?
