linux重启后raid消失,linux – CentOS 7创建的mdadm阵列在重启后消...

我使用以下磁盘和命令创建了一个raid1：

$ls -l /dev/disk/by-id/ata-ST3000*

lrwxrwxrwx 1 root root 9 Sep 19 07:27 /dev/disk/by-id/ata-ST3000DM001-9YN166_Z1F04NR1 -> ../../sdc

lrwxrwxrwx 1 root root 9 Sep 19 07:27 /dev/disk/by-id/ata-ST3000DM001-9YN166_Z1F190E3 -> ../../sda

$mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/disk/by-id/ata-ST3000DM001-9YN166_Z1F190E3 /dev/disk/by-id/ata-ST3000DM001-9YN166_Z1F04NR1

我将相关信息添加到mdadm.conf中.我使用’mdadm –detail –scan>> /etc/mdadm.conf’为ARRAY行：

$cat /etc/mdadm.conf

DEVICE /dev/disk/by-id/ata-ST3000DM001-9YN166_Z1F190E3

DEVICE /dev/disk/by-id/ata-ST3000DM001-9YN166_Z1F04NR1

ARRAY /dev/md0 metadata=1.2 name=jaime.WORKGROUP:0 UUID=93f2cb73:2d124630:562f1dd9:bf189029

MAILADDR your@address

我创建并挂载了文件系统：

$mkfs -t xfs /dev/md0

$mount -t xfs /dev/md0 /data

重新启动后,/ dev / md0不再存在,我无法组装数组：

$mdadm --assemble /
