-.Nd Events created by the ZFS filesystem
-.Sh DESCRIPTION
-Description of the different events generated by the ZFS stack.

-Most of these don't have any description.
-The events generated by ZFS have never been publicly documented.
-What is here is intended as a starting point to provide documentation
-for all possible events.
-.Pp
-To view all events created since the loading of the ZFS infrastructure
-(i.e, "the module"), run
-.Dl Nm zpool Cm events
-to get a short list, and
-.Dl Nm zpool Cm events Fl v
-to get a full detail of the events and what information
-is available about it.
-.Pp
-This manual page lists the different subclasses that are issued
-in the case of an event.
-The full event name would be
-.Sy ereport.fs.zfs.\& Ns Em SUBCLASS ,
-but we only list the last part here.
