安装大数据平台，每台机器需要挂载10个磁盘，用JBOD模式，操作系统为RHEL7.2。
写了两个脚本，format_disk.sh和mount_disk.sh实现磁盘自动分区格式化以及挂载，修改fstab。
format_disk.sh
#!/bin/bash
disks=(sdb sdc sdd sde sdf sdg sdh sdi sdj sdk)
for ((i=;i<${#disks[*]};i++))
do
mounted=`mount|grep "/mnt/${disks[i]}"`
if [ "$mounted" ] ; then
echo "umount /mnt/${disks[i]}"
umount /mnt/${disks[i]}
fi
echo "make partition /dev/${disks[i]}"
parted -s /dev/${disks[i]} mklabel gpt
parted -s /dev/${disks[i]} mkpart primary xfs % %
echo "format disk /dev/${disks[i]}"
mkfs.xfs -f -L ${disks[i]} /dev/${disks[i]}
done
echo -n "reboot?"
read ANS
case $ANS in
y|Y|yes|Yes)
echo "run mount_disk.sh after rebooting"
reboot
;;
n|N|no|No)
exit
;;
esac
mount_disk.sh
#!/bin/bash
rm -f fstab
cp /etc/fstab . -f
cat fstab
>fstab.new
sed -e '/\/mnt\/sd/d' fstab > fstab.new
cat fstab.new
disks=(sdb sdc sdd sde sdf sdg sdh sdi sdj sdk)
for ((i=;i<${#disks[*]};i++))
do
mounted=`mount|grep "/mnt/${disks[i]}"`
if [ "$mounted" ] ; then
echo "umount /mnt/${disks[i]}"
umount /mnt/${disks[i]}
fi
if [ ! -d "/mnt/${disks[i]}" ]; then
mkdir /mnt/${disks[i]}
fi
UUID=`lsblk -f /dev/${disks[i]}|grep "^${disks[i]} " |awk '{print $4}'`
if [ "$UUID" ]; then
echo "write partition to fstab.new"
echo "UUID=${UUID} /mnt/${disks[i]} xfs defaults 0 0" >> fstab.new
fi
done
cat fstab.new
echo -n "use this for /etc/fstab?"
read ANS
case $ANS in
y|Y|yes|Yes)
cp fstab.new /etc/fstab -f
mount -a
mount

n|N|no|No)
