磁盘如图这种方式

dm全是RAID1

怎么来检查各个部分是否都工作正常？怎么来看这两个磁盘是不是都工作正常？

Answer 1

首先谢谢上面两位：）

host:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/mapper/vg00-root /               ext3    errors=remount-ro 0       1
/dev/md0        /boot           ext3    defaults        0       2
/dev/mapper/vg00-swap none            swap    sw              0       0
/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto     0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0

关键是我在dmesg的时候出现这个信息

[    4.902949] md: raid1 personality registered for level 1
[    4.910474] md: md0 stopped.
[    4.916297] md: bind<sdb1>

[    4.970950] raid1: raid set md1 active with 1 out of 2 mirrors

还有 fdisk -l的时候出现这个信息

从上面的这些信息发现好像有点问题呢
