Estou executando o Ubuntu Server 12.04. Eu fiz o apt-get upgrade e recebi um aviso do mdadm.
update-initramfs: Generating /boot/initrd.img-3.11.0-24-generic
W: mdadm: the array /dev/md3 with UUID e3d153f0:6edf1702:1f51fb89:78ee93fe
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.
W: mdadm: the array /dev/md1 with UUID 76492e25:648c4dcd:1f51fb89:78ee93fe
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

Meu mdadm.conf atual é:
# mdadm.conf
#
# Please refer to mdadm.conf(5) for information about this file.
#
# by default, scan all partitions (/proc/partitions) for MD superblocks.
# alternatively, specify devices to scan, using wildcards if desired.
DEVICE partitions
# 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
# definitions of existing MD arrays

A configuração gerada por /usr/share/mdadm/mkconf é:
# mdadm.conf
#
# Please refer to mdadm.conf(5) for information about this file.
#
# by default (built-in), scan all partitions (/proc/partitions) and all

ARRAY /dev/md1 UUID=76492e25:648c4dcd:1f51fb89:78ee93fe
ARRAY /dev/md3 UUID=e3d153f0:6edf1702:1f51fb89:78ee93fe
O aviso diz que / dev / md1 e / dev / md3 não estão listados, mesmo que estejam na configuração. Está tudo bem mudar a configuração para o segundo ou isso vai causar problemas?
A única diferença que vejo é esta linha:
#DEVICE partitions
Isso é comentado no arquivo de configuração gerado, mas não no seu. Eu apenas descomentei isso e confirmei as mudanças. Avisos como esse tendem a ser uma coisa de "cabeça para cima" em vez de um problema real se as configurações se alinharem.
