Public bug reported:
Binary package hint: mdadm
Ubuntu 8.04.2, i386, server
Cannot stop RAID1 device. I do a disk cleanup and I want to replace
RAID1 device with RAID10 device. I cannot stop RAID1 device. /dev/md1
was used as a swap, but swap is "off" now.

My observation is that most documentation focus on creation of new RAID
devices but there is only little information about destruction of RAID
devices (that is needed sometimes...). I want to delete /dev/md1 and
create new /dev/md1 that will be RAID10 type. Should be an easy task but
I met an issue I cannot overcome...
