可否通过ob内部查看ob数据盘的大小呢？

select a.zone,concat(a.svr_ip,':',a.svr_port) observer,a.CPU_CAPACITY cpu_total, (CPU_CAPACITY-cpu_assigned) cpu_free, round(a.memory_limit/1024/1024/1024 ) mem_total_gb, round((memory_limit-mem_assigned)/1024/1024/1024) mem_free_gb, round(a.LOG_DISK_CAPACITY/1024/1024/1024) logdisk_total, round((a.LOG_DISK_CAPACITY-a.LOG_DISK_ASSIGNED)/1024/1024/1024) logdisk_free , round(a.DATA_DISK_CAPACITY/1024/1024/1024) data_total ,round((DATA_DISK_CAPACITY-a.DATA_DISK_IN_USE)/1024/1024/1024) data_free ,b.status,usec_to_time(b.start_service_time) start_service_time, usec_to_time(b.stop_time) stop_time ,b.build_version from GV$OB_SERVERS a join __all_server b on (a.svr_ip=b.svr_ip and a.svr_port=b.svr_port) order by a.zone, a.svr_ip; 这个是查看资源分配情况的。 也可以单独看磁盘参数 show parameters like '%datafile_disk%';——此回答整理自钉钉群：[社区]技术答疑群OceanBase
