milvus使用的etcd空间整理

环境说明:

docker compose部署的ETCD

 

1.查看etcd容器情况

[root@localhost milvus]# docker ps
CONTAINER ID   IMAGE                                      COMMAND                  CREATED      STATUS                PORTS                                                                                      NAMES
a0fb0801da2a   zilliz/attu:v2.4.6                         "docker-entrypoint.s…"   2 days ago   Up 2 days             0.0.0.0:8000->3000/tcp, :::8000->3000/tcp                                                  attu

2.登录容器
docker exec -ti 22e987f71758 /bin/bash

 

3.查看etcd情况

root@22e987f71758:/# ETCDCTL_API=3 etcdctl --endpoints="127.0.0.1:2379" --write-out=table endpoint status
+----------------+------------------+---------+---------+-----------+------------+-----------+------------+--------------------+--------+
|    ENDPOINT    |        ID        | VERSION | DB SIZE | IS LEADER | IS LEARNER | RAFT TERM | RAFT INDEX | RAFT APPLIED INDEX | ERRORS |
+----------------+------------------+---------+---------+-----------+------------+-----------+------------+--------------------+--------+
| 127.0.0.1:2379 | 8e9e05c52164694d |   3.5.5 |  221 kB |      true |      false |         3 |     467467 |             467467 |        |
+----------------+------------------+---------+---------+-----------+------------+-----------+------------+--------------------+--------+

 

4.查看压缩的版本
root@22e987f71758:/# ETCDCTL_API=3 etcdctl --endpoints="127.0.0.1:2379" endpoint status --write-out="json" | egrep -o '"revision":[0-9]*' | egrep -o '[0-9].*'
426301

 

5.压缩清理
root@22e987f71758:/# ETCDCTL_API=3 etcdctl --endpoints="127.0.0.1:2379" compact 426301
compacted revision 426301
# 整理多余的空间

root@22e987f71758:/# ETCDCTL_API=3 etcdctl --endpoints="127.0.0.1:2379" defrag
Finished defragmenting etcd member[127.0.0.1:2379]
