OCP服务宕掉以后要怎么拉起来？

[秋秋i]

【 使用环境 】 测试环境
【 OCP Express 】
【问题描述】使用obd一键部署的ocp express还有集群，ocp宕掉以后不知道如何重启，百度查了命令是obd cluster start ，但是我怎么知道OCP name是啥？

[辞霜]

～/.obd/cluster路径里面有对应集群名称

[秋秋i]

我不是要重启集群，我只是想单独把OCP express重新拉起来

[王利博]

obd cluster start name -c ocp express

但是我怎么知道OCP name是啥？

可以通过 obd cluster list 查看集群名称 然后 使用obd cluster start OCP name -c ocp-express

[秋秋i]

老师，这是什么原因导致ocp起不来？

[王利博]

提供下obd日志（~/.obd/log/obd）

有改什么配置文件参数么？

[秋秋i]

用obd一键部署是成功的，然后第二天ocp的日志就报错

现在我要单独重拉ocp，就拉不起来了

df -h && free -h 看下

如果可以登陆数据库可以再执行下：select a.zone, a.SVR_IP,a.SVR_PORT, b.status,cpu_capacity,cpu_assigned_max,cpu_capacity-cpu_assigned_max as cpu_free,round(memory_limit /1024/1024/1024 ,2) as memory_total_gb,round((memory_limit-mem_capacity) /1024/1024/1024 ,2) as system_memory_gb,round(mem_assigned /1024/1024/1024 ,2) as mem_assigned_gb,round((mem_capacity-mem_assigned) /1024/1024/1024 ,2) as memory_free_gb,round(log_disk_capacity /1024/1024/1024 ,2) as log_disk_capacity_gb,round(log_disk_assigned /1024/1024/1024 ,2) as log_disk_assigned_gb,round((log_disk_capacity-log_disk_assigned) /1024/1024/1024 ,2) as log_disk_free_gb,round((data_disk_capacity /1024/1024/1024 ),2) as data_disk_gb,round((data_disk_in_use /1024/1024/1024 ),2) as data_disk_used_gb,round((data_disk_capacity-data_disk_in_use) /1024/1024/1024 ,2) as data_disk_free_gb from gv$ob_servers a join oceanbase.DBA_OB_SERVERS b on a.zone=b.zone\G;

可以调整下资源

[秋秋i]

@王利博

df -h && free -h

老师，你觉得可能是51这个节点的磁盘空间不足导致46服务器的ocp express起不来吗？

[王利博]

有可能，可以提供下observer.log日志看看。
也可以使用obdiag进行下巡检和日志分析。

1. obdiag check 巡检
2. obdiag analyze log 日志分析
