Hello all, I feel as though I must be missing something that I have had no luck finding all morning. When setting up arrays with spares in a spare-group, I'm having no luck finding a way to get that information from mdadm or mdstat. This becomes an issue when trying to write out configs and the like, or simply trying to get a feel for how arrays are setup on a system. Many tutorials/documentation/etc etc list using `mdadm --scan --detail >> /etc/mdadm/mdadm.conf` as a way to write out the running config for initialization at reboot. There is never any of the spare-group information listed in that output. Is there another way to see what spare-group is included in a currently running array? It also isn't listed in `mdadm --scan`, or by `cat /proc/mdstat` I've primarily noticed this with Debian 7, with mdadm v3.2.5 - 18th May 2012. kernel 3.2.0-4. When I modify the mdadm.conf myself and add the 'spare-group' setting myself, the arrays work as expected, but I haven't been able to find a way to KNOW that they are currently running that way without failing drives out to see. This nearly burned me after a restart in one instance that I caught out of dumb luck before anything of value was lost.
