Troubleshooting ramdisk run
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Connect to the remote console as described in `Troubleshooting PXE boot`_ to
see what is going on with the ramdisk. The ramdisk drops into emergency shell
on failure, which you can use to look around. There should be file called
``logs`` with the current ramdisk logs.
First, check if the ramdisk logs were stored locally as described in the
`Troubleshooting data processing`_ section. If not, ensure that the ramdisk
actually booted as described in the `Troubleshooting PXE boot`_ section.
Finally, you can try connecting to the IPA ramdisk. If you have any remote
console access to the machine, you can check the logs as they appear on the
screen. Otherwise, you can rebuild the IPA image with your SSH key to be able
to log into it. Use the `dynamic-login`_ or `devuser`_ element for a DIB-based
build or put an authorized_keys file in ``/usr/share/oem/`` for a CoreOS-based
one.
