It seems that dmeventd was created to allow lvm to have it monitor
mirrored volumes and detect errors and take appropriate action, such as
notifying the administrator about the mirror becoming degraded and maybe
rebuilding with a spare.  I can't find any documentation on how to
configure this though, so I get the feeling that it has not been
implemented.  Is this the case?

Currently it has snapshot and mirror (raid1) plugins. The mirror part
does monitor (event based) for failed legs or logs and takes some
actions. At the moment, all of its configuration is in /etc/lvm/lvm.conf
file. Look at activation section.

1) It doesn't notify the admin.
2) It doesn't automatically rebuild with a given sparse disk. Although
   you can use "allocate" to get this kind of feature. I have not
   tested this feature though!

Ahh there it is, all described in the conf file comments.  Just wasn't
described in the man page for it.  Thanks.
