原milvdb模拟无法启动只剩下volumes目录的恢复

环境:
OS:Centos 7
milvus:2.4.6

1.停掉原有的milvus
确保原有的milvusdb里有数据,方便恢复的时候验证

[root@host135 milvus]# docker compose down
WARN[0000] /home/middle/milvus/docker-compose.yml: `version` is obsolete 
[+] Running 5/5
 ? Container attu               Removed                                                                        0.9s 
 ? Container milvus-standalone  Removed                                                                       11.0s 
 ? Container milvus-etcd        Removed                                                                        0.9s 
 ? Container milvus-minio       Removed                                                                        1.5s 
 ? Network milvus               Removed

2.准备新环境目录(我这里是同一台机器上,所以目录需要与原来的不一样)
[root@host135 middle]# mkdir -p /home/middle/milvus_new

3.准备docker-compose.yml文件
若能找得到原有的docker-compose.yml最好,若没有的话,可以直接从如下目录进行下载
https://github.com/milvus-io/milvus/releases/tag/v2.4.6

我这里保留有原来的 docker-compose.yml,直接使用即可

拷贝到新的部署目录
[root@host135 milvus]# cp docker-compose.yml /home/middle/milvus_new/

4.准备好milvus.yaml
因为我原来的部署是把milvus.yaml外挂到宿主机了的,所以新环境也需要准备好该文件
[root@host135 milvus]# cp milvus.yaml /home/middle/milvus_new/

5.拷贝原有的环境的 volumes 目录到新环境
[root@host135 milvus]# cp -r volumes /home/middle/milvus_new/

6.启动新环境

[root@host135 milvus_new]# cd /home/middle/milvus_new
[root@host135 milvus_new]# docker compose up -d
