megacli64做raid1

先卸载raid0的12块盘，再做raid1，其中下面的一行要确认

#megacli64 -PDList -aALL | egrep 'Enclosure Device ID|Slot Number'

#!/bin/bash
sed -i /nodiratime/d /etc/rc.local
echo "/dev/sdb               /data/slot0          xfs     defaults        0 0" >> /etc/fstab
echo "/dev/sdc               /data/slot1          xfs     defaults        0 0" >> /etc/fstab
echo "/dev/sdd               /data/slot2          xfs     defaults        0 0" >> /etc/fstab
echo "/dev/sde               /data/slot3          xfs     defaults        0 0" >> /etc/fstab
echo "/dev/sdf               /data/slot4          xfs     defaults        0 0" >> /etc/fstab
echo "/dev/sdg               /data/slot5          xfs     defaults        0 0" >> /etc/fstab
