Question

我在寻求一种解决办法,即改变多克数据集。

OS is Ubuntu 18.04.5.
Docker version is 20.10.1.

Without changes docker works fine, but I need to change the data-root to get more space. I found two possible solutions:

Setting a symlink to /var/lib/docker
Creating /etc/docker/daemon.json with data-root value set (including service restart and daemon-reload)

这两种解决办法都没有奏效,也留下同样的错误。例如,当我执政时

docker run hello-world

I get the error
"Error response from daemon: symlink /proc/mounts /mnt/docker/aufs/mnt/[...]-init/etc/mtab: function not implemented"

页: 1

docker run mysql

I get
"docker:failed to register layer: Error processing tar file(exit status 1): symlink hostname /bin/dnsdomainname: function not implemented"

我已把安装在/etc/fstab的装置上。

UUID=<uuid>    /mnt    auto    auto,user,rw    0 0

至今对数据储存进行罚款。 only只发生 do。

能否在磁盘上获得许可?

我最后把外部储存归为延伸4.mkfs.ext4 /dev/mmcblk0。
