Hello folks,

I'm trying to discover if ZFS under FreeBSD will automatically pull in a 
hot spare if one is required.

This raised the issue back in March 2010, and refers to a PR opened in 
May 2009

* http://lists.freebsd.org/pipermail/freebsd-fs/2010-March/007943.html
* http://www.freebsd.org/cgi/query-pr.cgi?pr=134491

In turn, the PR refers to this March 2010 post referring to using devd 
to accomplish this task.


Does the above represent the the current state?

I ask because I just ordered two more HDD to use as spares.  Whether 
they sit on the shelf or in the box is open to discussion.
