Inodes

• Inodes are VFS abstraction for the file

• Inode has operations (iii_methods)

• VFS maintains an inode cache, NOT the individual FS’s (compare NT, BSD etc)

• Inodes contain an FS specific area where:

  • ext2 stores disk block numbers etc
  • AFS would store the FID

• Extraordinary inode ops are good for dealing with stale NFS file handles etc.
