Chrome Version: 59.0.3071.93
OS: CrOs  9460.61.0	

What steps will reproduce the problem?
(1) Add storage and unlimitedStorage permissions to a chrome app.
(1) Fill up the device, I used `df -h` to get available space in /var then ran `fallocate -l 50M /var/log/big_file` to fill it up almost all the way.
(2) Use  chrome.storage.local.set(...) to fill it up the rest of the way, until you get an error. IO error: ... FILE_ERROR_NO_SPACE...
(3) Try to use chrome.storage.local.remove(...) to remove data saved in previous step.

What is the expected result?
You should be able to remove the data to help clear space.

What happens instead?
You get an error, there is no space to remove an element:
Unchecked runtime.lastError while running storage.remove: IO error: .../000120.ldb: FILE_ERROR_NO_SPACE (ChromeMethodBFE: 3::WritableFileAppend::8)


This bug makes it possible to fill up a device too far, and then not be able to fix it because you can no longer remove items from storage.

Cannot workaround and stop saving before filling up due to this bug:
