Subject: [PATCH] Detail: handle non-existent arrays better.
|
|
|
|
If you call "mdadm --detail" with a device file for an array which
|
|
doesn't exist, such as by
|
|
mknod /dev/md57 b 9 57
|
|
mdadm --detail /dev/md57
|
|
|
|
you get an unhelpful message about and inactive RAID0, and return
|
|
status is '0'. This is confusing.
|
|
|
|
So catch this possibility and print a more useful message, and
|
|
return a non-zero status.
