Operating System:

File system operations may involve modifying multiple disk blocks. For example, to create a new file in an existing directory, OS needs to (1) allocate an inode, mark the used inode bitmap; (2) allocate data blocks, mark the used data block bitmap; (3) associate data blocks with the file by modifying the inode; (4) add inode to the given directory by modifying the directory file; (5) write data blocks.

(1) What kinds of inconsistency can take place if the system is interrupted between the multiple operations necessary to complete the operation of creating a new file?

(2) How does the journaling file system maintain data consistency in the scenario you just identified in (1)?
