Didn't Bartosz look into this in the context of ARC++?

Consensus is we should add a policy to disable these warnings for users. To maxkirsch to prioritize since it'll mostly impact EDU users once we roll ARC out.

I have no sense of the urgency for this so off to Naveen in case he does

I've seen another occurrence of this issue where the low disk space notification is appearing for files stored by previous users.  Attaching logs from the device here.

Re #2: Maybe I'm lacking context, but shouldn't we just fix free space management instead of disabling warnings?

There are a few issues, tracked internally at b/31992808.

Main issue is: for a consumer device, we want to warn before we start blowing away local data (i.e. kid starts downloading large video, want to warn before we delete Mom's photos). For a shared EDU device, the contract is slightly different: when you sign out and give the device to another user, you are implicitly saying that you don't care about any cached data on the device.

There's no way to "fix free space management" that addresses both of these cases well - best we've come up with is to identify shared enterprise devices and disable warnings by policy.

But if you have ideas, definitely do share them - I don't think anyone is wed to the current plan of record, we just haven't come up with a better solution.

Oh, and I think there's some wonky mismatch between ARC and CrOS where ARC may warn for disk space before CrOS cleanup kicks in. Apparently this is also by design.

Thanks for the context.  I guess there's no requirement to have a single heuristic that works in all contexts.  Why don't we use different strategies depending on whether it's a consumer or an enterprise device, and potentially even allow enterprise admins to configure the strategy of their choice?

Should this be merged into issue 656788?

Yes, feels like it should. WDYT, Naveen? If you agree, mark this as a dupe.

@Naveen, could you reply to #c8 and update the status of this bug.

Our school board is experiencing this disk space cleanup failure problem (along with several other boards).  See issue 582490.
