Drive Almost Full - 456.74GB out of 457.45GB used ... what happens next.

Anyone have any idea what happens the drive finally is full on the miner? I've been watching the drive space dwindle now for the last couple of weeks and I'm pretty sure that sometime between Sunday and Wednesday of this week it's finally going to happen. So that said what will happen, will the units, die, will there be an automatic FIFO delete?

Is there a good idea of what can be deleted via SSH'ing into the box, I don't use the node but it has run and I'm sure there is data in there that could free up some space if someone can tell me what to delete that won't cripple the miner.

Looking for suggestions.

Thanks
