Ahh... I missed that. My memory is that when the array is inactive, the
md driver really don't know anything about the array. It doesn't find
out until it reads the metadata, and it does that as it activates the
array.
But looking at your sample output I see does, as you say, give a raid
level for an inactive array.
But looking at the code, it should do exactly the same thing for
--export, and --brief, and normal.
It determines the raid level:
if (inactive && info)
str = map_num(pers, info->array.level);
else
str = map_num(pers, array.level);
and then report 'str' in all 3 cases (possibly substituting "-unknown-"
or "container" for NULL) providing that array.raid_disks is non-zero -
which it is in your example.
So I cannot see how you would get the results that you report.
Do you know how you got the array in this inactive state? I could then
experiment and see if I can reproduce your result.
