Question

Homework 13:

In a file system using metadata journaling for crash consistency, what would the sequence of write operations be to disk to create “file100” in the directory structure in Homework 11?

How would it differ from that of data journaling? Using the same format as for Homework 12, identify what data or metadata is written and where it is being written.

Format of HW12 Journal Write: Transaction Begin(TxB) record, file X data

Homework 11: File System Reads and Writes Suppose we have a directory structure as follows: Root Directory Directory A Directory B Directory C File5 File1 File Suppose the contents of the root directory and its inode, and the contents of directory A and A's inode, are cached in main memory. List out all the disk read and write operations (to directories, files, inodes) needed to create a new 1 fie called "file100" in directory A Explain the reason for each read and write. For example, if the root inode and the root directory was not cached, you would have a line item that says the following: Read rootinode determine location of root directory on disk
