docker with btrfs ubuntu
我需要帮助才能使用btrfs启动docker deamon。
当我尝试使用-s btrfs启动它时，deamon不想启动。 在尝试使用btrfs启动docker deamon时，日志中存在错误（错误的文件系统？）。
我使用Ubuntu作为操作系统：
root@ionutmos-VirtualBox:/etc/default# uname -a Linux ionutmos-VirtualBox 3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux 我使用/ var / lib / docker2上的btrfs挂载了一个新的分区。
/dev/sda btrfs 52428800 512 50302720 1% /var/lib/docker2
我有1.6.2泊坞窗版本安装：
/etc/default# docker version Client version: 1.6.2 Client API version: 1.18 Go version (client): go1.4.2 Git commit (client): 7c8fca2 OS/Arch (client): linux/amd64 Server version: 1.6.2 Server API version: 1.18 Go version (server): go1.4.2 Git commit (server): 7c8fca2 OS/Arch (server): linux/amd64
我编辑了“/lib/systemd/system/docker.service”文件，看起来像这样：
Description=Docker Application Container Engine Documentation=http://docs.docker.com After=network.target docker.socket Requires=docker.socket [Service] EnvironmentFile=-/etc/default/docker ExecStart=/usr/bin/docker -d -H fd:// $OPTIONS MountFlags=slave LimitNOFILE=1048576 LimitNPROC=1048576 LimitCORE=infinity [Install] WantedBy=multi-user.target Also=docker.socket
我在/ etc / default / docker文件中插入了2个选项：
OPTIONS="--storage-driver btrfs" DOCKER_OPTS="-s btrfs"
当我尝试手动启动docker deamon时，这个错误出现在日志中：
FATA[0000] Shutting down daemon due to errors: error intializing graphdriver: prerequisites for driver not satisfied (wrong filesystem?)
这里是整个日志文件：

阿德里安·穆阿特的调教是我的问题的答案。
在我开始之后，Docker开始使用btrfs：
/usr/bin/docker -d -g /var/lib/docker2
非常感谢你。
