W: mdadm: the array /dev/md/imsm0 with UUID metadata=imsm
W: mdadm: is currently active, but it is not listed in mdadm.conf. if
W: mdadm: it is needed for boot, then YOUR SYSTEM IS NOW UNBOOTABLE!
W: mdadm: please inspect the output of /usr/share/mdadm/mkconf, compare
W: mdadm: it to /etc/mdadm/mdadm.conf, and make the necessary changes.
mdadm.conf 설정이 제대로 되어 있는지, 재부팅 해도 되는지 궁금합니다.
아래는 자동 생성된 /etc/mdadm/mdadm.conf 의 내용입니다.

Please refer to mdadm.conf(5) for information about this file.
by default (built-in), scan all partitions (/proc/partitions) and all
containers for MD superblocks. alternatively, specify devices to scan, using
wildcards if desired.

auto-create devices with Debian standard permissions
CREATE owner=root group=disk mode=0660 auto=yes
automatically tag new arrays as belonging to the local system
HOMEHOST <system>
instruct the monitoring daemon where to send mail alerts
MAILADDR root
