Redhat操作系统磁盘挂载

1.在所有节点安装必要软件

yum -y install bc

2.执行命令查看每个节点未挂载的磁盘清单DEVICE_LIST

fdisk -l

3.修改脚本1中的DEVICE_LIST

#!/bin/sh
#请按照实际硬件填写DEVICE_LIST
DEVICE_LIST="/dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg /dev/sdh"
for DEVICE in $DEVICE_LIST
do
echo "*** create partition for $DEVICE ***"
parted -s $DEVICE mklabel gpt mkpart gpt2t xfs 0% 100%
PARTITION="$DEVICE""1"
echo "*** formatting $PARTITION ***"
mkfs.xfs -f $PARTITION
done

4.修改脚本2中的PARTITION_LIST

#!/bin/sh
#备份/etc/fstab
cp /etc/fstab /etc/fstab.bak
#请按照实际硬件填写PARTITION_LIST
PARTITION_LIST="sdb1 sdc1 sdd1 sde1 sdf1 sdg1 sdh1"
index=0
for PARTITION in $PARTITION_LIST
do
UUID=`blkid "/dev/""$PARTITION" | awk '{print $2}' | sed 's/"//g'`
echo "*** UUID $UUID ***"
echo "*** add $PARTITION to /etc/fstab ***"
index=`echo $index+1|bc`
MOUNTDIR="/srv/bigdata/disk"$index
echo "mkdir -p $MOUNTDIR"
mkdir -p $MOUNTDIR
echo "*** appending "$UUID $MOUNTDIR xfs defaults 0 0" to /etc/fstab ***"
echo "$UUID $MOUNTDIR xfs defaults 0 0" >> /etc/fstab
echo ""
done
#mount all partition
mount -a
#show mounted partitions
df -h

5.执行脚本1，然后执行脚本2（每个节点）
