CSE 120: Homework #4 Solutions

We have 10 direct pointers that each point directly to a 4K data block, so we can point to 10 * 4K = 40K with the direct pointers.

We have one single-indirect pointer that points to a 4K disk block (an "index block") which contains nothing but pointers to data blocks. Since each disk block pointer is 4 bytes, the index block can hold 4K / 4 = 1K pointers to data blocks. So, the single-indirect pointer indirectly points to 1K * 4K = 4M (2 10 * 2 12 = 2 22 bytes).

We have one double-indirect pointer that points to an index block that contains 1K pointers to more index blocks. These leaf index blocks each contain 1K pointers to data blocks. So, the double-indirect pointer indirectly points to 1K * 1K * 4K = 4G (2 10 * 2 10 * 2 12 = 2 32 bytes).

Adding everything up, the maximum file size is 40K + 4M + 4G.

The zip program puts one or more compressed files into a single zip archive, along with information about the files (name, path, date, time of last modification, protection, and check information to verify file integrity).

In general, the archive program cannot guarantee that the file will be restored to the same inode.

User programs like zip and tar use the logical file system (filenames and directories). inodes are part of the physical file system (superblock and inodes). The logical file system is built on top of the physical file system, and, in general, the kernel only provides a syscall interface for the logical file system.

So if an archive program wanted to guarantee that a file is restored to its original inode, it would have to write directly to the hard disk (bypassing the file system entirely), since there is no syscall interface to write to a particular inode. This means that the archive program would need root access, and it would need to understand the layout of the physical file system on the hard disk.

In particular, writing a file to its original inode becomes very difficult if the original inode is in use by some other file f . The archive program would have to relocate f to another inode, which is hard because the archive program would have to search the disk for all references to f 's old inode, and make them all point to f 's new inode. This is extremely difficult if the file system is mounted and there are other running processes that use the file system.

For various values of I and X , compute the percentage of time that the program spends waiting for I/O and fill in the following table. If I and X are both 1 ms, for example, then the program spends 50% of its time waiting for I/O.
