Docker容器扩容

1.查看容器硬盘信息

dmsetup table /dev/mapper/docker-253:2-12884901952-b0bb11eebeb997e2abdcc50caaffe8bbe07d67544e150954d6830344affa5dac

2.输出值

echo $((20*1024*1024*1024/512))

3.echo上面所获得的值，更改原10G扩容到20G

echo 0 41943040 thin 253:3 645 | dmsetup load /dev/mapper/docker-253:2-12884901952-b0bb11eebeb997e2abdcc50caaffe8bbe07d67544e150954d6830344affa5dac

4.激活硬盘

dmsetup resume docker-253:2-12884901952-b0bb11eebeb997e2abdcc50caaffe8bbe07d67544e150954d6830344affa5dac

5.调整文件系统的大小（xfs硬盘类型）

xfs_growfs /dev/mapper/docker-253:2-12884901952-b0bb11eebeb997e2abdcc50caaffe8bbe07d67544e150954d6830344affa5dac

6.重启docker容器

docker stop docker-project

docker start docker-project

（如果启动时报错，则继续执行下列语句）

- 6.1、echo 0 41943040 thin 253:3 645 | dmsetup load /dev/mapper/docker-253:2-12884901952-b0bb11eebeb997e2abdcc50caaffe8bbe07d67544e150954d6830344affa5dac

- 6.2、dmsetup resume docker-253:2-12884901952-b0bb11eebeb997e2abdcc50caaffe8bbe07d67544e150954d6830344affa5dac
