Has anyone gotten this strange behavior corrected with Google? We have been seeing this and have had to turn on the erase all local data for all of our Chromebooks. This in turn increases the login time as all of the extensions have to be reloaded onto the Chromebook every time a student logs into it. We are seeing this with each student being assigned a Chromebook, so only one user is on the device for the entire year. To test if they had fixed the issue I had turned the Erase all local data off on two OUs that had about 58 Chromebooks in it on Friday afternoon. Today when the students got back every one of those Chromebooks were at 100% disk usage and causing issues.
