我使用 mdadm 使用两个 3TB 驱动器创建了 RAID 1 阵列。经过一整夜的这个过程后,我发现两个 3TB 驱动器 /sdb 和 /sdc 从文件资源管理器中消失了。重新启动系统后它们重新出现,然后在再次重新启动后再次消失,它们似乎已损坏,在 GParted 中发现错误,它们位于:
Corrupt extent header while reading journal super block</i>
<i>Unable to read the contents of this file system!
Because of this, some operations may be unavailable.
The cause might be a missing software package.
The following list of software packages is required for ext4 file system support: e2fsprogs v1.41
我将新的 RAID 阵列命名为 md0,它现在在 /mnt/md0 中有一个文件夹,它是空的。
/etc/mdadm 中有一个 conf 文件,内容如下:
# mdadm.conf
#
# !NB! Run update-initramfs -u after updating this file.
# !NB! This will ensure that initramfs has an uptodate copy.
#
# 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.
#DEVICE partitions containers
# 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
# This configuration was auto-generated on Mon, 24 Dec 2018 02:28:48 -0500 by mkconf
ARRAY /dev/md0 metadata=1.2 name=dna-computer:0 UUID=df25e6e6:cccb8138:aa9f4538:31608c33
不确定这是否有帮助,但命令cat /proc/mdstat
如下:
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
unused devices: <none>
