我正在学习 docker,我正在使用 v1.11.0 我试图安装 hadoop,但 devmapper 抱怨空闲的磁盘空间?
devmapper: Thin Pool has 82984 free data blocks which is less than minimum required 163840 free data blocks. Create more free space in thin pool or use dm.min_free_space option to change behavior
我已经删除了所有图片,但问题依然存在:
[root@localhost hadoop_docker]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
debian latest 47af6ca8a14a 3 weeks ago 125 MB
[root@localhost hadoop_docker]#
and this is my disk configuration:
[root@localhost ~]# lsblk

如何释放磁盘空间?
