泊塢窗devicemapper存儲空間

正在錯誤而刪除容器「留在設備上沒有空間」。泊塢窗devicemapper存儲空間

# docker rm orientdb1 
Error response from daemon: Driver devicemapper failed to remove root filesystem ba18ea8014b6024eb738502612130244ff363b433f146102c64eb2eb0f3a321c: devmapper: Error saving transaction metadata: devmapper: Error creating metadata file: open /var/lib/docker/devicemapper/metadata/.tmp636968871: no space left on device

這是「df -kh」輸出的片段。

Filesystem    Size Used Avail Use% Mounted on 
/dev/mapper/centos-root 3.8T 3.8T 20K 100%/

這是「du -ksh」輸出的片段。這表明使用了3.8TB。

3.8T /var/lib/docker

這是「碼頭信息」輸出。

相信磁盤空間的數字是針對在所述環回模式中使用由devicemapper環回驅動程序和文件/ var/lib中/搬運工/ devicemapper/devicemapper /數據。

清理泊塢窗，你可以在一個較新的版本上運行docker system prune。老版本可以用這樣的命令：

docker ps -aqf status=exited | xargs docker rm 
docker images -qf dangling=true | xargs docker rmi

除此之外，您將需要通過容器和圖像去docker stop，docker rm在容器上，並docker rmi在圖像上。
