# 创建文件系统
1. 查看未格式化的磁盘，执行**fdisk -l**
2. 格式化磁盘和逻辑卷 
   **mkfs.xfs /dev/vdb**
   **mkfs.xfs /dev/vdc**
   **mkfs.xfs /dev/vde**
   创建文件系统目录
   **执行：mkdir -p /usr/sap /hana/log /hana/data /hana/share**
   获取磁盘的UUID： **blkid**

   在/etc/fstab创建挂载点
   **echo "UUID=662\*\*\*\*\*\*81dbf9783 /usr/sap xfs defaults 0 0" \>\>/etc/fstab**
   **echo "UUID=0c5\*\*\*\*\*\*\*\*19734f /hana/log xfs defaults 0 0" \>\>/etc/fstab**
   **echo "UUID=3ae\*\*\*\*\*\*05166 /hana/share xfs defaults 0 0" \>\>/etc/fstab**
   
   
   
3. 创建LVM卷 
   执行以下命令
   **pvcreate /dev/vdd /dev/vde**
   **vgcreate vghana /dev/vdd /dev/vde**
   **vgdisplay vghana**

   **lvcreate -i 2 -l 100%VG -n lvhanadata vghana**
   **mkfs.xfs /dev/mapper/vghana-lvhanadata**
   **uuid3=\`blkid /dev/mapper/vghana-lvhanadata \| awk '{print $2}'\|awk -F"\\"" '{print $2}'\`**
   **echo "UUID=$uuid3 /hana/data xfs defaults 0 0" \>\> /etc/fstab**
   挂载所有磁盘 **mount -a** ,再执行**df -h**查看磁盘挂载情况
