根据提供的日志信息，obd cluster start myoceanbase 启动集群失败，具体错误信息如下：

1. 在启动前的检查阶段，start_check_pre 函数中出现了错误，导致启动失败。
2. 错误信息中没有具体的错误原因，建议查看详细的 OBD 日志以获取更多信息。

解决步骤：

1. 查看详细的 OBD 日志：
   您可以使用 obd display-trace 命令查看详细的 OBD 日志，以便更准确地定位问题。具体命令如下：

   obd display-trace 6723ec32-73f5-11f0-a848-20fadb829a14
   

2. 检查系统资源：

   • 内存资源： 确保系统有足够的可用内存。可以从日志中看到 cat /proc/meminfo 的输出，检查 MemAvailable 是否足够。如果内存不足，可以尝试释放缓存或调整 memory_limit 和 system_memory 参数。
   • 磁盘空间： 确保各个挂载点有足够的磁盘空间。从日志中可以看到 df --block-size=1024 的输出，特别是 / 分区的可用空间非常少（56209408 KB），这可能是导致启动失败的原因之一。

3. 检查配置文件：

   • 确认配置文件中的参数设置是否合理，特别是 memory_limit 和 system_memory 参数。通常情况下，memory_limit/3 ≤ system_memory ≤ memory_limit/2。如果设置不合理，可以通过 obd cluster edit-config 命令进行调整。

4. 参考官方文档：

   • 如果上述步骤仍无法解决问题，可以参考 OceanBase 官方文档 中的相关错误码和解决方案。

希望这些步骤能帮助您解决问题。如果仍有疑问，请提供更多详细的日志信息。

检索到的文档如下:

1. 使用命令行进行运维
2. 错误码

ocp-express当前已经不建议部署了，该组件不进行维护了建议删掉
