>You have an easy way to fix it, just delete the spacer file. But what good does that do? You solve the issue right then and there. Step 1. realize there is a space issue and get to terminal Step 2. free space so any solution has memory Step 3. Solve by doing <??? specifics ???>

So if your alarm sounded when there was 8 GB of free disk space (instead of 0 GB), then you could still respond in the same amount of time and you would still have an additional 8 GB worth of padding while you determined the root cause. The only difference is that you wouldn't need to actually go in and delete the spacer file (and potentially have downtime in the time it takes you to delete the spacer file). Another way to think of this is that you have the 8 GB spacer file, but when the disk fills up the spacer file is automatically deleted and your alarm goes off. Which is literally the same as having your alarm go off when free disk space reaches 8 GB.

  The thing you are still missing is that no matter how you set your alarms, by the time you respond the disk can still be completely full.

    The spacer solution guarantees you will always have one instance of "disk got full", even if the fill rate is slow. With an alarm there is a chance you end up solving the problem with zero instances of "disk got full" if the fill rate is not that big. That is the main difference.

  It isn't though. Whatever rogue process is generating the garbage so quickly has likely thrown and died (potentially leaving other, useful processes, able to continue work). Not 100%, of course, but there's a solid chance that the garbage will stop being generated. Also, forcing manual intervention has a psychological effect. An alarm that goes off at 8 GB remaining? Eh, I'll get to it at some point. A "disk is full, error, error, everything is broken"? I will deal with it -right now-, especially since I know a fix. Do that, with an alarm at 16 GB (so I still get the early alert in the event I'm that good a citizen and actually prioritize getting to the bottom of it even though it's caused no issue yet), and I'm in a better position still.

Let me try to explain what the other person is saying. If you have an 8gb spacer file, at some point the disk will get full and cause some errors, so you will have to log in, remove the spacer file and then deal with the problem. If you have an alarm for 8gb remaining, you will receive the alarm before any application ever notices the disk is full. You will have basically the same amount of time to solve the problem for good, but if you're able to solve it before these 8gb also ends, you won't have to deal with any "app crashed/misbehaved because it reached a point where no space was available" issues.

  Your described scenario is no different than when you would have set your first warning at 16GB disk space, except that you won't have to scramble to delete the roadblock halfway between here and the crash zone.
