When I try to execute

navigator.webkitPersistentStorage.requestQuota(1024 * 1024 * 1024 * 15, function (bytes) {
        console.log('Successfuly allocated ' + bytes + ' bytes of persistant storage.');
        }, function (e) {
            console.log('Failed to allocate persistant storage!');
        });

then Chrome will allocate only 10737418240 bytes which is exactly 10GB, but I asked for 15GB. Of course, I did click "allow" to allocate more storage. Has anybody met this problem?

EDIT: I don't see any reason why somebody has downvoted my question. The reason why I want to allocate that much data, is that our application must store large amount of medical images. 10GB is definitely not enough. Furthermore, from :

Maximum storage space -- As large as the available space on the hard drive. It has no fixed pool of storage.

EDIT2: NO, my disk is not full. Available space is around ~110GB.

• 6 why would you ever want to store that much. that's an unreasonable amount, I'm surprised it lets you do anywhere near 10GB – DLeh Commented Oct 6, 2015 at 13:15

• Disk full? I thought the limit for local storage was somewhere around 5MB... – GolezTrol Commented Oct 6, 2015 at 13:28
• It's not local storage. Local storage and persistent storage are two pletely different types of HTML5 storage.... I have edited my question, explained why we need such large amount of data. – Signum Commented Oct 6, 2015 at 13:31
• Are you sure chrome wont actually create more storage as it gets filled? I mean, it seems stupid to reserve a file the size of everything remaining on the hard drive, that would make the puter inoperable. Maybe when you fill up the ten it will slowly expand and then ask for storage permissions again once you hit 15? – somethinghere Commented Oct 6, 2015 at 13:45

I have reported bug to Google. Turns out that max persistent storage quota is indeed 10GB, but documentation saying "As large as the available space on the hard drive" is incorrect.
