Low disk space message should only show up once (or a few times)

[Michael Zanetti]

Today morning I woke up and had the notifications area full with low disk space warnings (See attached screenshot). I think it should only appear once until the user confirms/clears it. It the user then still doesn't free up some space it's fine to show it again after a while, but not every hour.

I consumed 96% of the disk, got the warning message once. I left the phone for days and never saw any additional reports.

From examining the code it has a check to see if the warning has been issued for that disk and will not repeat it. The only path I see is if the consumption goes back under 95% and then back over.

Any ideas on how you triggered it? Do you have anything cleaning files on the device?

hmm... good question. By now I use a bigger SD card and so I haven't seen this in a long time. But back then I surely did not have any special tasks set up to clean files.

In <https://wiki.ubuntu.com/Storage#Storage_problems>, I wrote:
————————————
Unless otherwise specified, the alert should appear whenever the warning state is in effect, and either:

* the alert has not opened since the warning state began, and has not been dismissed in the past 5 minutes; or
* the alert box has not been open in the past 30 minutes.

In particular, an alert should close by itself whenever the warning state is no longer in effect.

If storage warnings are currently implemented as notifications, the notification equivalent of “should close by itself” is “should be deleted”. So if “the consumption goes back under 95% and then back over”, then the notification should be deleted at the point that consumption goes under 95%.
