One thing, in the section "md device line" you describe how to identify
spare devices,
but you didn't mention the "(S)" which appears after a spare device, at
least it does on mine:
# uname -a
Linux pecan.makuch.org 2.6.23.1-21.fc7 #1 SMP Thu Nov 1 21:09:24 EDT
2007 i686 i686 i386 GNU/Linux
# cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md0 : active raid5 etherd/e0.0[0] etherd/e0.2[9](S) etherd/e0.9[8]
etherd/e0.8[7] etherd/e0.7[6] etherd/e0.6[5] etherd/e0.5[4]
etherd/e0.4[3] etherd/e0.3[2] etherd/e0.1[1]
3907091968 blocks level 5, 64k chunk, algorithm 2 [9/9] [UUUUUUUUU]
[==================>..] resync = 91.0% (444527040/488386496)
finish=560.9min speed=1301K/sec
unused devices: <none>
Unless that means something else??? But e0.2 is my spare so I'm just
assuming "(S)" means spare!
Thanks
Mike
