Hardware node boot hangs with the following output on a screen:
init: rcS main process terminated with status 1 Entering non-interactive startup Starting dkms:
DKMS hangs on start because root partition is out of free space. This might often happen after a hardware node crash - memory dump might take all the free space available in root partition.
Boot the server into a single-user mode and clean up root partition. If space was consumed by a memory dump generated by
kdump consider configuring alternative path with sufficient disk space.
