(1)启动时,如果是两个节点的集群,那么需要在每个节点上,用root用户执行:hastart,然后使用hastatus来查看启动过程中资源的状态信息
(2)停止时,只需要在其中一个节点上,使用root用户执行:hastop -all,同样是使用hastatus来查看状态,这个需要在每个节点上确认VCS已经停止完毕
注意:不管是启动,还是停止,VCS的日志是一定要查看,尤其是启动时,可以帮助排查启动过程中的问题。默认的VCS日志文件:
/var/VRTSvcs/log/engine_A.log
这是我经常使用的。何谓冻结,通俗的来说,就是让VCS暂时不管理集群,即使监控到有节占上资源组状态不正确,也不会发生切换或重新拉起操作。在维护中经常使用到,比如:oracle数据库打补丁、重启监听之类。
<strong>冻结双机:</strong> RMCDB02:~ # hagrp -freeze RCS_DB_SG RMCDB02:~ # hastatus -sum -- SYSTEM STATE -- System State Frozen A RMCDB01 RUNNING 0 A RMCDB02 RUNNING 0 -- GROUP STATE -- Group System Probed AutoDisabled State B RCS_DB_SG RMCDB01 Y N ONLINE B RCS_DB_SG RMCDB02 Y N OFFLINE -- GROUPS FROZEN -- Group C RCS_DB_SG -- RESOURCES DISABLED -- Group Type Resource H RCS_DB_SG Application ora_raw H RCS_DB_SG Application ora_vg H RCS_DB_SG IP ora_ip H RCS_DB_SG NIC ora_nic H RCS_DB_SG Netlsnr ora_listener H RCS_DB_SG Oracle ora_ora11g <strong>解冻双机:</strong> RMCDB02:~ # hagrp -unfreeze RCS_DB_SG
这个也是我经常使用到的。主要是监控到集群内主机可能出现故障,所以人为有计划的将资源组切换到另外一个节点中;或者是硬件维护、系统重启。
NDMCDB04:~ # hastatus -sum -- SYSTEM STATE -- System State Frozen A NDMCDB03 RUNNING 0 A NDMCDB04 RUNNING 0 -- GROUP STATE -- Group System Probed AutoDisabled State B RCS_NDMCDB_RG NDMCDB03 Y N ONLINE B RCS_NDMCDB_RG NDMCDB04 Y N OFFLINE NDMCDB04:~ # hagrp -switch RCS_NDMCDB_RG -to NDMCDB04 ## 将资源从NDMCDB03切换到NDMCDB04主机上
