A UNIX-type file-system uses a disk block size of 1KB, 128 byte inodes, and 32 bit disk addresses. If the inode contains 64 bytes of data, 8 direct, 1 indirect, 1 double-indirect, and 1 triple- indirect blocks, apart from other file information. How many disk blocks would be required for storing files of sizes (a) 1 byte (b) 1024 bytes (c) 64 KB (d) 1MB ?

Consider a file system that uses inodes to represent
files. This file system has 16 direct disk blocks, as well as
single, double, and triple indirect disk blocks. This file system
is illustrated in the below figure. Please notice that the tables
pointed to by the indirect pointers are full sized blocks that only
stores pointers.

Given a Ext3 filesystem that uses: - 32 bit addresses, - 512 byte blocks on disk, - 16 direct addresses and - up to a level 3 indirection Answer the following questions: 1) How many blocks does a 12KiB file need? 2) What is the largest file size (in KiB) that does not need indirect block references? 3) What is the largest file size (in KiB) possible using only single indirection? 4) A file that is 1104 bytes in size,...

Part B
Consider a file system that uses a structure similar to an i-node with the following differences. If the file size is less than 100 bytes, the data is stored directly in the i-node. If it is larger, there are 8 direct links (point to a data block), 2 single-indirect links, 1-double indirect links and 1 triple indirect link. What is the largest file size that can be indexed in this system? Assume the block size is 1024 bytes....

Q1) A particular implementation of UNIX operating system provides the file structure modelled in the Figure 1. Here the i-node for the file contains certain information such as the access permissions for the file. This is followed by the entries that contain information about where the file is located on the storage device. The first 10 entries are the addresses of blocks where actual data for the file are stored. If block can contain 512 bytes of information, then these...

Operating Systems Concepts Assume we have a system wherein directory entries can hold up to 16 disk block addresses. For files that are not larger than 16 blocks, the 16 addresses are used as an index table for the file. For files that are larger than 16 blocks, the addresses point to indirect blocks which in turn point to 256 file (data) blocks each. Assume further that a block is1024 bytes. Please calculate how large a file could be (in...

A file system control block has the following address method: 10 direct block address, 10-bit single indirect address, and 10-bit double indirect address. The block size is 8K bytes. What address method will be used for the data files of 100K, 10M, and 10G bytes respectively? List the detailed computation to justify your answer.
