为什么Docker卷空间不足？ [英] Why has Docker volume run out of space?

问题描述

Dockerized数据库将不再启动，因为...

Dockerized database will no longer start because...

FATAL:  could not write lock file "postmaster.pid": No space left on device

虽然我坚信某物空间已用完。在尝试从备份还原45Gb数据库之后，首先出现了此问题。在这段时间内，我的 Docker.qcow2 文件膨胀到60Gb。 Hypervisor对该VM文件的大小有一定限制吗？在Mac上使用Docker。

There are hundreds of Gb available on my hard-disk although I do believe something has run out of space. This problem first cropped up after a couple of attempts at restoring a 45Gb database from backup. During that time my Docker.qcow2 file ballooned to 60Gb. Does Hypervisor have some limit on the size of that VM file? Using Docker for Mac.

这似乎是从 docker-compose.yml中删除这些行时出现某种错误的线索：

volumes:
  - website_database_volume:/var/lib/postgresql/data

（是的，我理智地检查了自己是否位于文件的右侧，并弄乱了其他属性）

(and yes I sanity checked I was in the right part of the file by messing with other attributes)

docker系统df
