报错信息：

harbor-db容器重启报错：initdb: error: directory “/var/lib/postgresql/data/pg13“ exists but is not empty

现象：

在重启docker服务或者通过docker-compose重启harbor服务时，harbor-db容器都一直处于Restarting状态，无法恢复UP状态。

Harbor版本：v2.3.2

查看日志：

1.查看harbor所有容器启动日志路径

[root@k8s-master harbor]# vim harbor.yml
...
112 # Log configurations
113 log:
114   # options are debug, info, warning, error, fatal
115   level: info
116   # configs for logs in local storage
117   local:
118     # Log files are rotated log_rotate_count times before being removed. If count is 0, old versions are remov    ed rather than rotated.
119     rotate_count: 50
120     # Log files are rotated only if they grow bigger than log_rotate_size bytes. If size is followed by k, the     size is assumed to be in kilobytes.
121     # If the M is used, the size is in megabytes, and if G is used, the size is in gigabytes. So size 100, siz    e 100k, size 100M and size 100G
122     # are all valid.
123     rotate_size: 200M
124     # The directory on your host that store log
125     location: /var/log/harbor        //Harbor所有容器运行的日志存放路径

2.查看harbor-db容器启动日志

[root@k8s-master harbor]# cat /var/log/harbor/postgresql.log | tail -20
...

Oct 13 08:14:22 172.23.0.1 postgresql[28777]: with an argument other than "/var/lib/postgresql/data/pg13".

解决：

1.从上面日志中的提示directory "/var/lib/postgresql/data/pg13" exists but is not empty可以清楚/var/lib/postgresql/data/pg13这个目录存在，并且不为空，但是在宿主机上找不到这个目录。

[root@k8s-master harbor]# ll /var/lib/postgresql/data/pg13
ls: 无法访问/var/lib/postgresql/data/pg13: 没有那个文件或目录

2.于是想到查看一下docker-compose的yaml文件，查看一下harbor-db容器的挂载目录的信息。

[root@k8s-master harbor]# vim docker-compose.yml
...
postgresql:
    image: goharbor/harbor-db:v2.3.2
    container_name: harbor-db
    restart: always
    cap_drop:
      - ALL
    cap_add:
      - CHOWN
      - DAC_OVERRIDE
      - SETGID
      - SETUID
    volumes:
      - /home/harbor/data/database:/var/lib/postgresql/data:z     //挂载目录信息
    networks:
      harbor:
    dns_search: .
    env_file:
      - ./common/config/db/env
    depends_on:
      - log
    logging:
      driver: "syslog"
      options:
        syslog-address: "tcp://127.0.0.1:1514"
        tag: "postgresql"
...

3.从docker-compose.yaml文件中可以看到宿主机上的/home/harbor/data/database目录挂载到容器中的/var/lib/postgresql/data目录下，那会不会是/home/harbor/data/database目录不为空呢？删除掉它试试。

[root@k8s-master harbor]# rm -rf /home/harbor/data/database

4.删除/home/harbor/data/database目录后将harbor运行的容器删除，在重新创建并启动。

[root@k8s-master harbor]# docker-compose down -v

registry            /home/harbor/entrypoint.sh       Up
registryctl         /home/harbor/start.sh            Up

可以看到harbor-db已经启动成功，恢复正常了。

原因：

1.出现如上的原因很大可能是之前在这台机器上安装过Harbor服务，第一次安装的时候在挂载目录下创建了数据，再次安装时需要将之前的脏数据都清空才可以；

2.还遇到过一种情况，那就是在清理了挂载目录的脏数据之后重启docker服务或者使用docker-compose重启Harbor服务时，harbor-db容器还是一直处于Restarting状态，这种情况下可以将Harbor所有容器都down -v删除掉，修改harbor.yaml中data_volume数据挂载目录，再重新up -d（成功过）。或者换一个Harbor的版本，实测Harbor v2.1.1版本可以（之前是Harbor v2.3.2）。
