Scenario "Kihei": Surely Not Another Disk Space Scenario

This is interesting as I cheesed it by making the datafile a sparse one as it's just zero-filled, then I watched replays and found there are two 1 GB unused disks and figured that would be the intended solution.

This could be prevented by filling the datafile with random data and check the content, but I guess it's not needed for fun's sake.

Hello, thanks for your comment. The idea behind the files filled with zeros is to make clear that they can be deleted safely (vs deleting possible production data).

[HarukaMa]

Are you referring to a different scenario? the check script explicitly checked that the 5GB file is not deleted and the apparent size has not changed.

[fduran]

Ah sorry, yes, was confused with "Manhattan" where you can delete the files.

When I tried to strace -f ./kihei, the console terminated immediately. When I opened again, I see below image. is it expected?

[fduran]

Hello @JoeHO888 , this scenario runs with asciinema for the replay feature and it breaks when running strace or under some other conditions. We haven't found yet a good solution for this kind of issue.

Yeah, this seems to happen sporadically, haven't been able to find a pattern, sometimes it's after running the first strace and other times you can run it 10 times and nothing would happen.
My assumption is that it fills up the disk completely, preventing SSH; you'll need to destroy and recreate the server.
