由于需要将磁盘划分为两个raid，一是raid 1用于安装操作系统，另一个是raid 5用于存放大量数据，由于Dell powerEdge R730xd，不支持开机界面组建多raid，只能进入系统使用megacli来操作查看已有raid 信息，目前是针对操作系统做了一个raid 1

可以看出已经有一个target id为0，一个target id为1的两个raid了，至此raid组建完毕
parted用于格式化大于1T的raid磁盘，文件系统为xfs
- [root@ns-xxx ~]# parted /dev/sdb
- (parted) mklabel
- New disk label type? gpt
- Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue?
- Yes/No? yes
- (parted) mkpart
- Partition name? []? registry
- File system type? [ext2]? xfs
- Start? 0%
- End? 100%
- (parted) quit
- Information: You may need to update /etc/fstab.
格式化后，查看信息
