五，lsblk
六，fdisk
sudo fdisk /dev/sda
g 大于２TB的磁盘必须使用GPT模式的分区表（配合UEFI）
n 创建分区（GPT没有扩展分区和逻辑分区　可以创建128个分区）
w　保存
sudo mkfs.ext4 -F /dev/sda1
sudo vi /etc/fstab
/dev/sda1 /data_raid1 ext4 defaults 0 0
/dev/sdc1 /ceph_disk1 ext4 defaults 0 0
/dev/sdd1 /ceph_disk2 ext4 defaults 0 0
/dev/sde1 /ceph_disk3 ext4 defaults 0 0
sudo mount -a
df
七，hwinfo

服务器上的磁盘已经分区了 各个盘的目的如下：
/dev/sdb1 RAID1 安装了OS
/dev/sda1 RAID1 挂在 /data_raid1 8TB 保存比较重要的数据
/dev/sdc1 RAID0 挂在 /ceph_disk1 8TB 测试ceph分布式集群
/dev/sdd1 RAID0 挂在 /ceph_disk2 8TB 测试ceph分布式集群
/dev/sde1 RAID0 挂在 /ceph_disk3 8TB 测试ceph分布式集群
