The lockfs is a really neat feature to deny certain accesses to your filesystem without unmounting it completly. Some locks are more useful for general use than other other. For example the write lock is really useful, when you want to freeze the content of the filesystem.

though it should NOT be used on / filesystem,
and yes it is used in most of the SVM tasks like mirroring data volume etc...
I've pasted a link where you'll find lockfs is used
