docker 使用 btrfs ubuntu
docker with btrfs ubuntu
我需要帮助才能使用 btrfs 启动 docker 守护程序。
当我尝试使用 -s btrfs 启动它时,守护进程不想启动。尝试使用 btrfs 启动 docker 守护程序时,日志中出现错误(错误的文件系统?)。
我使用 ubuntu 作为 OS :
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
我在 /var/lib/docker2 上使用 btrfs 安装了一个新分区。
/dev/sda btrfs 52428800 512 50302720 1% /var/lib/docker2
我安装了 1.6.2 docker 版本:
/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,它看起来像这样:
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 守护程序时,此错误出现在日志中:
FATA[0000] Shutting down daemon due to errors: error intializing graphdriver: prerequisites for driver not satisfied (wrong filesystem?)
这是整个日志文件:

Docker 我是这样开始使用btrfs的:
/usr/bin/docker -d -g /var/lib/docker2
非常感谢。
