mdadm配置没问题吗？

我已经安装了一个新的 raid 10 /dev/md123，我想确保 raid 阵列在重新启动后正常。

我原来的 mdadm.config 是

# mdadm.conf written out by anaconda
MAILADDR root
AUTO +imsm +1.x -all
ARRAY /dev/md/boot level=raid1 num-devices=2 UUID=fd36f8a9:d02a1229:c11a8feb:ac529491
ARRAY /dev/md/home level=raid10 num-devices=4 UUID=5d619c21:250f4f48:2bfe1c59:0d832a9d
ARRAY /dev/md/root level=raid1 num-devices=2 UUID=ca8c432a:beca45c5:cd4ecca3:91723196
ARRAY /dev/md/swap level=raid1 num-devices=2 UUID=6a86f000:9ce02893:6f27b781:d3815dcd

我跑完后mdadm --detail --scan --verbose >> /etc/mdadm.conf得到了这个

# mdadm.conf written out by anaconda
MAILADDR root

ARRAY /dev/md/boot level=raid1 num-devices=2 UUID=fd36f8a9:d02a1229:c11a8feb:ac529491

   devices=/dev/sdg1,/dev/sdh1,/dev/sdi1,/dev/sdj1

可以吗mdadm.config还是我应该删除重复的行/home /boot /swap
