Last night when I tried to shut down my laptop it wouldn’t shut down. When I clicked the shutdown icon the screen would just grey but no confirmation prompt to shutdown as would normally come up. In the end I had to just force it off by pressing and holding the power button as my battery was about to die anyway.
Now when I try boot I get an error saying that there is a problem with the filesystem (not /) and that I need to manually repair it. I’m presented with the command line root login prompt. When logging in I am I then get a filesystem repair prompt. What do I do from here?
Is there a general disk / filesystem repair utility that I can run from this prompt? It’s not obvious which partition is the problem although it does say not /.
