OCP V4.4.2

我尝试手动启动obshell

export OB_ROOT_PASSWORD="xxxxx*";./bin/obshell admin start --ip x.x.x.x --port 2886



[ERROR] Code: Agent.Rebuild.VersionNotSame, Message: Take over or rebuild failed: Agent version is not the same, agent version in all_agents: 4.2.5.1-12025010214, agent version now: 4.4.0.0-32026010814
[ERROR] Code: Agent.Daemon.StartFailed, Message: Daemon start failed: obshell server exited with code 22, please check obshell.log for more details

我对比了待扩容节点（任务失败节点）与正常运行的observer节点的obshell版本

待扩容节点： 
./bin/obshell -V
OBShell 4.4.0.0 (for OceanBase_CE)
