Comment 24 for bug 1916482

The fix works for me too, and Antelope appears to have the fix in it, though the order of the code is not what is listed in https://review.opendev.org/c/openstack/glance_store/+/885581 and causes the fix not to work.

By default install it is showing up as:
    def _resize_on_write(self, image, image_size, bytes_written, chunk_length):
        """Handle the rbd resize when needed."""
        if image_size != 0 or self.size >= bytes_written + chunk_length:
            return self.size
        new_size = self.size + self.resize_amount
        LOG.debug("resizing image to %s KiB" % (new_size / units.Ki))
        image.resize(new_size)
        # Note(jokke): We double how much we grow the image each time
        # up to 8gigs to avoid resizing for each write on bigger images
        self.resize_amount = min(self.resize_amount * 2, 8 * units.Gi)
        return new_size

Where it should be:

def _resize_on_write(self, image, image_size, bytes_written, chunk_length):
    """Handle the rbd resize when needed."""
    if image_size != 0 or self.size >= bytes_written + chunk_length:
        return self.size
    self.resize_amount = min(self.resize_amount * 2, 8 * units.Gi)
    # Note(jokke): We double how much we grow the image each time
    # up to 8gigs to avoid resizing for each write on bigger images
    new_size = self.size + self.resize_amount
    LOG.debug("resizing image to %s KiB" % (new_size / units.Ki))
    image.resize(new_size)
    return new_size

The order appears to be wrong, self.resize_amount is in the wrong position during install, but in the right oder in https://review.opendev.org/c/openstack/glance_store/+/885581
