Maximum file size given a particular inode structure?

Question

Suppose a UNIX file system has some constraints--say, 2 KB blocks and 8B disk addresses. What is the maximum file size if inodes contain 13 direct entries, and one single, d

Answer 1

How many pointers in 1 block?

     each block is 2kb = 2^11
     1 disk address is 8b = 2^3
     So, in 1 block there are 2^11/2^3 = 2^8 pointers"
    

How many pointers in the file system?

     for 13 direct entries = (2^8)*13 = 3328
     for single  = (2^8)^2 = 2^16
     for double = (2^8)^3 = 2^24
     for triple = (2^8)^4 = 2^32
     total pointer is :3328 + 2^16 + 2^24 + 2^32"
     

Therefore the size of the file system is:

size of the disk is  : total of pointer*size of the pointer , which is around 34 GB "
