docker –storage-opt dm.basesize = 40G不起作用？
我将存储切换到devicemapper，并尝试将容器的rootfs增长到40G。
我添加以下configuration到/ var / lib / boot2docker / profile并重新引导boot2docker的VM
[/var/lib/boot2docker/profile start]<br> \#!/bin/sh<br> EXTRA_ARGS="--storage-opt dm.basesize=40G --storage-driver=devicemapper"<br> [/var/lib/boot2docker/profile end]<br> docker.log显示configuration正在生效
[/var/lib/boot2docker/docker.log snippet start]<br> /usr/local/bin/docker -d -D -g "/var/lib/docker" -H unix:// -H tcp://0.0.0.0:2376 **--storage-opt dm.basesize=40G --storage-driver=devicemapper** --tlsverify --tlscacert=/var/lib/boot2docker/tls/ca.pem --tlscert=/var/lib/boot2docker/tls/server.pem --tlskey=/var/lib/boot2docker/tls/serverkey.pem >> "/var/lib/boot2docker/docker.log"<br> 2014/12/22 03:33:36 docker daemon: 1.3.2 39fa2fa; execdriver: native; graphdriver: devicemapper<br> [74c56fa4] +job serveapi(unix:///var/run/docker.sock, tcp://0.0.0.0:2376)<br> [debug] deviceset.go:565 Generated prefix: docker-8:1-784941<br> [debug] deviceset.go:568 Checking for existence of the pool 'docker-8:1-784941-pool'<br> [debug] deviceset.go:587 Pool doesn't exist. Creating it.<br> [/var/lib/boot2docker/docker.log snippet end]<br>
但是，容器的rootfs仍然绑定到20G而不是configuration中显示的40G
[df -h in container start]<br> [root@sshd ~]\# df -h<br> Filesystem Size Used Avail Use% Mounted on<br> rootfs **20G** 401M 19G 3% /<br> /dev/mapper/docker-8:1-784941-8184b64c9275276c9420f5decd0b1d31dc8bce725ecbd93a918407363b45b2d3<br> 20G 401M 19G 3% /<br> tmpfs 2.0G 0 2.0G 0% /dev<br> shm 64M 0 64M 0% /dev/shm<br> /dev/sda1 192G 6.9G 175G 4% /etc/resolv.conf<br> /dev/sda1 192G 6.9G 175G 4% /etc/hostname<br> /dev/sda1 192G 6.9G 175G 4% /etc/hosts<br> tmpfs 2.0G 0 2.0G 0% /proc/kcore<br> [root@sshd ~]\#<br>
[容器端的df -h]
–storage-opt dm.basesize似乎不工作，我该如何解决这个问题？
事实certificate，新的dm.basesize只适用于我拉一个新的形象。 它没有工作，因为我使用“docker加载</ xxx”加载本地备份焦油图像。
