11gR2 removing a mirrored Oracle Cluster Registry and adding again I want to test a scenario where one of my OCR file is lost. This is what I have done. Now lets have a look at my OCR configuration. /u01/app/11.2.0/grid/bin/ocrcheck Status of Oracle Cluster Registry is as follows : Version : 3 Total space (kbytes) : 262120 Used space (kbytes) : 2708 Available space (kbytes) : 259412 ID : 2044210075 Device/File Name : /u02/ocfs2/ocr/OCRFile Device/File integrity check succeeded Device/File Name : /u02/ocfs2_mirror/ocr/OCRFile Device/File integrity check succeeded Device/File not configured Device/File not configured Device/File not configured Cluster registry integrity check succeeded Logical corruption check succeeded As you can see Ive two mirrored OCR files one on /u02/ocfs2/ path and another on /u02/ocfs2_mirror/. For your information, these paths are on two different LUNs formed by several disks and on a RAID-1 configuration Here is where my mirrored OCR file exists...
