File systems on the system where the shutdown was issued are immediately unmounted. As a result, data is synched to disk. For shared file systems, one of the following actions is done on the file systems that are owned by the system where the command was issued.

• Unmount if automounted or if a file system was mounted on an automounted file system.
• Move to another system if an AUTOMOVE was specified.
• Unmount for all other file systems.
