Several tests assume a certain amount of disk space free after the reserve block pool is filled. Changing the default size of the reserve block pool breaks these tests because there is less space available that first thought. Change these tests to specify a known reserve block pool size of 1024 blocks to ensure that they continue to work correctly even if the default size changes.
