Can you also post the preclear logs? I've made a change so the divide by zero will not happen, but we need to find out why there is no available space. Something is clobbering the rootfs.
Do the following:
Post the output of the 'ls -la /' command.
Reboot in safe mode.
Post the results of the 'df /' command.
If the command shows expected results, you'll need to find out which plugin, VM, or Docker Container is messing with rootfs. You may have a misconfigured path.
