853502 - Report disk partition fullness during automated tests

Status: RESOLVED FIXED

(Testing :: General, defect)

Description

[Geoff Brown [:gbrown]]

If a disk partition becomes full during a test, various failures may result:
 - application installation failure
 - profile creation failure
 - disk cache write failure
 - database update failure
My recent experience with a nearly-full /data partition suggests that some of these failures can go undetected, resulting in seemingly random test failures.

How full are the partitions on the tegras and pandas normally? During tests? What if something goes wrong and we log a lot more than usual?

I would like to add disk partition info to our test logs -- maybe just add df output to the existing sutagent DEVINFO command.

There was some existing support for reporting disk usage, but it wasn't complete. I have changed it to my liking -- what do you think?

I like it. Don't forget to update mozdevice as well so we have an API to this data!

Thanks Will. Actually, mozdevice already supports getInfo("disk") -- I think there's no need for mozdevice changes in this case.
