今天是2014-03-28，继续写RAC的内容，今天写的是如何恢复损坏的表决磁盘（votedisk）和OCR。
首先查看目前状态：
[root@rac-two bin]# ./ocrcheck Status of Oracle Cluster Registry is as follows : Version : 3 Total space (kbytes) : 262120 Used space (kbytes) : 3472 Available space (kbytes) : 258648 ID : 152256349 Device/File Name : +GIDG Device/File integrity check succeeded Device/File not configured Device/File not configured Device/File not configured Device/File not configured Cluster registry integrity check succeeded Logical corruption check succeeded [root@rac-two bin]# ./crsctl query css votedisk ## STATE File Universal Id File Name Disk group -- ----- ----------------- --------- --------- 1.

模拟votedisk和ocr损坏。

开始进行恢复：
停止crs资源。
