Consider the organization of a unix file as represented by, Ask an Expert

Engineering

Consider the organization of a UNIX file as represented by the inode (Figure 12.14). Assume that there are 12 direct block pointers, and a singly, doubly, and triply indirect pointer in each inode. Further, assume that the system block size and the disk sector size are both 8K. If the disk block pointer is 32 bits, with 8 bits to identify the physical disk and 24 bits to identify the physical block, then

a. What is the maximum file size supported by this system?

b. What is the maximum file system partition supported by this system?

c. Assuming no information other than that the file inode is already in main memory, how many disk accesses are required to access the byte in position 13,423,956?
