Hi, Mikael, hi guys!


Follow the errors found after building the new version of mdadm:

#mdadm --stop /dev/md/ubuntu\:md-raid6_primary

#mdadm --assemble --force /dev/md/ubuntu\:md-raid6_primary /dev/sdaa
/dev/sdac /dev/sdf /dev/sdg /dev/sdh /dev/sdi /dev/sdj /dev/sdz

mdadm: device /dev/md/ubuntu:md-raid6_primary exists but is not an md array.
