由于需要处理的硬盘太多，所做的重复操作太多，写成脚本parted.sh方便。

# /dev/sda|b|d|e|g|h|i|j|k|l 分别是10块硬盘，/dev/sdc 和 /dev/sdf 是用做 journal 的 SSD：

# vi parted.sh
#!/bin/bash
set -e
if [ ! -x "/sbin/parted" ]; then
    echo "This script requires /sbin/parted to run!" >&2
    exit 1
fi
DISKS="a b d e g h i j k l"
for i in ${DISKS}; do
    echo "Creating partitions on /dev/sd${i} ..."
    parted -a optimal --script /dev/sd${i} -- mktable gpt
    parted -a optimal --script /dev/sd${i} -- mkpart primary xfs 0% 100%
    sleep 1
    #echo "Formatting /dev/sd${i}1 ..."
    mkfs.xfs -f /dev/sd${i}1 &
done
SSDS="c f"
for i in ${SSDS}; do
    parted -s /dev/sd${i} mklabel gpt
    parted -s /dev/sd${i} mkpart primary 0% 20%
    parted -s /dev/sd${i} mkpart primary 21% 40%
    parted -s /dev/sd${i} mkpart primary 41% 60%
    parted -s /dev/sd${i} mkpart primary 61% 80%
    parted -s /dev/sd${i} mkpart primary 81% 100%
done
