AWS 磁盘 扩容

官方详细文档 [https://docs.aws.amazon.com/zh_cn/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html]
a) 针对只有一块磁盘的服务器

df -h
lsblk
growpart /dev/nvme0n1 1
root_disk_type=$(df -hT|awk '$7 == "/"{print $2}')
if [ ${root_disk_type} = "xfs" ];then
    xfs_growfs -d /
    df -h
else
    resize2fs /dev/nvme0n1p1
    df -h
fi

b) 针对两块磁盘的服务器
实战
服务器上有多挂载一块硬盘给elasticsearch,并且挂载到路径 /elasticsearch

lsblk
growpart /dev/nvme1n1 1
root_disk_type=$(df -hT|awk '$7 == "/elasticsearch"{print $2}')
if [ ${root_disk_type} = "xfs" ];then
    xfs_growfs -d /elasticsearch
    df -h
else
    resize2fs /dev/nvme1n1p1
    df -h
fi
