问题描述/异常栈
万象数据库出现服务异常告警，agent-common 出现database space exceeded 关键字 
[251102.115831][MainThread] E  Error when update agent config with etcd. <class 'grpc._channel._InactiveRpcError'>/<_InactiveRpcError of RPC that terminated with:
        status = StatusCode.RESOURCE_EXHAUSTED

发现版本
万象数据库-3.3.7.3
解决方案
临时方案：压缩并清理etcd存储数据 长期方案：升级ETCD服务，开启自动压缩清理 
# 临时方案操作步骤
## 登录etcd容器
docker exec -it mysql-paas-etcd /bin/bash
## 执行压缩
rev=`etcdctl --endpoints=$ETCD_LISTEN_CLIENT_URLS endpoint status --write-out="json" | egrep -o '"revision":[0-9]*' | egrep -o '[0-9].*'`

result=`etcdctl --endpoints=$ETCD_LISTEN_CLIENT_URLS compact "${rev}"`

## 此命令可能出现超时，等待10分钟左右重试一般可执行成功
result=`etcdctl --endpoints=$ETCD_LISTEN_CLIENT_URLS defrag`

size=`etcdctl --endpoints=$ETCD_LISTEN_CLIENT_URLS endpoint status|awk -F ',' '{print $4}'`
echo "压缩后的etcd数据大小如下"
echo $size


# 长期方案参考灵犀文档：https://docs.popo.netease.com/lingxi/382da0713ab84b579fad3bf188ec85c5
问题原因
etcd未开启自动压缩清理功能，导致数据持续增长直到超出存储空间配额。
