Package: mdadm
Version: 2.6.7.2-3
Severity: normal
Hello,
I repeatedly run into trouble trying to nuke ill-configured drives to
make them usable again (lest these bogus RAIDs show up eg. in d-i and
prevent me from properly configuring the drives).
I am already aware of 'mdadm --zero-superblock' and friends, but have to
note that these just don't work. Eg. I was unable to use this command
from a shell, spawned from d-i, to remove bogus RAID0 superblocks from
the drives.
I got error messages like this:
~ # mdadm --zero-superblock --force /dev/sda
mdadm: Couldn't open /dev/sda for write - not zeroing
Kind regards,
--Toni++

I think this is designed behaviour — you would not want to zero
a superblock on a device that is potentially still in use.
Hence closing this bug report.
