Docker nfs 卷 mysql - 如何修复："failed to copy file info"

Question

我用 docker 创建了一个 "mysql" 服务 - 与一个 nfs 卷组合。服务未启动并出现以下错误：


"failed to copy file info for /var/lib/docker/volumes/db_data/_data: failed to chown /var/lib/docker/volumes/db_data/_data: lchown /var/lib/docker/volumes/db_data/_data: operation not permitted"

我试过 "couchdb" 但它有同样的问题

下面是一段示例代码：

version: "3.7"
networks:
  web:
    external: true
services:
  db:
    image: mysql:5.7
    networks:
      - web
    environment:
      MYSQL_ROOT_PASSWORD: xxxxxx
      MYSQL_DATABASE: xxxxxx
      MYSQL_USER: xxxxxx
      MYSQL_PASSWORD: xxxxxx
    volumes:
      - db_data:/var/lib/mysql
volumes:
  db_data:
    driver_opts:
      type: nfs
      o: addr=x.x.x.x,nolock,soft,rw
      device: :/var/nfs/db_data

让它发挥作用的正确和最佳方法是什么？

Answer 1

尝试从服务器端修复它！在 NFS 服务器上，检查“/etc/exports”文件。你应该有这样的东西：

/var/nfs/db_data x.x.x.x/24(rw,sync,no_subtree_check)

尝试添加 "no_root_squash" 选项：

/var/nfs/db_data x.x.x.x/24(rw,sync,no_root_squash,no_subtree_check)
