What is a "hot spare" on FreeNAS?

Solution 1
Yes, that is exactly what a hot spare is. The hot spare drive would occupy a drive bay and could be assigned to one or more data pools (global spare), and would automatically start a rebuilding process in the event of a failed disk.
This is in contrast to a cold spare drive, that would sit outside of the server/enclosure in order to be swapped manually when there's a failure.

the FreeNAS docs are the best place to get this information. Take a look: http://doc.freenas.org/index.php/Volumes

Dan almost 12 yearsI used
zpool add raid-5x3 spare ada0
, and nowzpool status
lists ada0 as a spare. But is that it? No need to format, create a volume, etc? -
ewwhite almost 12 yearsNope. Not much else to do. I also saw the note about spares not working properly in FreeNAS. I would check on that just to make sure... However, spares have always functioned well in my Solaris and Nexenta ZFS environments.
