创建文件系统
- 查看未格式化的磁盘,执行fdisk -l
- 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
- 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
