YFS

This is a file system called Yet Another File System (yfs), which supporta basic file operation, fault tolerant, version control and support concurrent request from different clients.

Lab1

• This part implements an inode manager to support the basic file system with operations like CREATE/GETATTR, PUT/GET, REMOVE.

Lab2

• This part implements file system implementation with FUSE operations like CREATE/MKNOD, LOOKUP, READDIR, SETATTR, WRITE, READ, MKDIR, UNLINK and SIMBOLIC LINK.

Lab3

• This part uses RPC to implement a single client file server.

Lab4

• This part implememnt a lock server.
• Add locking to ensure that concurrent operations to the same file/directory from different clients occur one at a time.

Lab5

• This part adds support for version control operations based on log.

Lab6

• This part implement Paxos and use it to agree to a sequence of membership changes (i.e., view changes).

Lab7

• This part provides the yfs with the ability of fault tolerance using erasure code.
