Hi List,

i have multiple technicians computers where I need the md-modules f.e.
for recoveries and such.  But these computers are also used to just
diagnose failing drives.

Now I have the effect that upon plugging in drives that formerly were
part of an array, the md_mod modules gets loaded and tries to
auto-assemble arrays.  This disturbs the diagnosis.

I've tried raid=noautodetect as kernel commandline, and I grepped the
source for the MODULE_PARM_DESC macro, which yielded no (useful) result.
 This "automagic" behaviour happens since 2.6.36.

Is there any way to turn it off - i.e. that I need to explicitly issue
mdadm commands to bind any drive to any array?

Cheers,
Stefan
