This exercise demonstrates the point at which 32 bits is no longer enough to locate an inode anywhere in the filesystem.
Show that 32 bits are required for a 1kB inode located in a 4TB filesystem.
Slightly increase the size of the file to increase the AG size by seeking to 31 blocks beyond 4TB. The increased AG size has increased the inode size to 33 bits, it is no longer possible to place a 32 bit inode anywhere in the filesystem.
