CRS-0184: Cannot communicate with the CRS daemon.----一步步解决（OCR问题）
刚刚装好的10g RAC，重启一下，等了很久，数据库还是没起来，然后：
[oracle@rac1 ~]$ crs_stat -t -v CRS-0184: Cannot communicate with the CRS daemon.
不科学呀，首先习惯性的检查了盘的状况：
[root@rac1 log]# ll /dev/raw/* crw-rw---- 1 oracle dba 162, 1 Nov 1 12:56 /dev/raw/raw1 crw-rw---- 1 oracle dba 162, 2 Nov 1 12:56 /dev/raw/raw2 crw-rw---- 1 oracle dba 162, 3 Nov 1 12:56 /dev/raw/raw3 crw-rw---- 1 oracle dba 162, 4 Nov 1 12:56 /dev/raw/raw4 crw-rw---- 1 oracle dba 162, 5 Nov 1 12:56 /dev/raw/raw5 crw-r----- 1 root oinstall 162, 6 Nov 1 12:56 /dev/raw/raw6 crw-r----- 1 root oinstall 162, 7 Nov 1 12:56 /dev/raw/raw7 crw-r----- 1 root oinstall 162, 8 Nov 1 12:56 /dev/raw/raw8
没问题呀，跟我装的时候一模一样。那好，我开始专业DBA的套路了，看日志！
[root@rac1 ~]# cd /u01/crs/oracle/product/10.2.0/app/log/ [root@rac1 log]# cd rac1/ [root@rac1 rac1]# ll total 28 drwxr-x--- 2 oracle oinstall 4096 Oct 31 11:36 admin -rw-rw-r-- 1 root oinstall 3864 Oct 31 17:43 alertrac1.log drwxr-x--- 2 oracle oinstall 4096 Oct 31 19:19 client drwxr-x--- 2 root oinstall 4096 Oct 31 11:39 crsd drwxr-x--- 4 oracle oinstall 4096 Oct 31 15:39 cssd drwxr-x--- 2 oracle oinstall 4096 Oct 31 17:20 evmd drwxrwxr-t 5 oracle oinstall 4096 Oct 31 17:42 racg现在时间是11月1号，而日志却没有在11月1号改变，不甘心，于是每个目录进去看，都没有在今天改变过（试验机，用完后都是关机，故不会有日志变化）。
这个不科学。。。。。。既然没有cluster日志，那么是不是操作系统层面都没过？于是：
[root@rac1 ~]# cd /var/log/ [root@rac1 log]# vi messages ... Nov 1 14:36:23 rac1 logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.2826. Nov 1 14:36:23 rac1 logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.2977. Nov 1 14:36:23 rac1 logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.3005. Nov 1 14:37:24 rac1 logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.2977.

Diagnostics in /tmp/crsctl.2826.
有戏！
[root@rac1 log]# vi /tmp/crsctl.2826 Failure -2 opening file handle for (ocr1) Failure 1 checking the CSS voting disk 'ocr1'. Failure -2 opening file handle for (ocr2) Failure 1 checking the CSS voting disk 'ocr2'. Failure -2 opening file handle for (ocr3) Failure 1 checking the CSS voting disk 'ocr3'. Not able to read adequate number of voting disks
好吧，原来是这样。莫非我磁盘权限设置不对?改权限：
KERNEL=="raw1", OWNER="oracle", GROUP="oinstall", MODE="660" KERNEL=="raw2", OWNER="oracle", GROUP="oinstall", MODE="660" KERNEL=="raw3", OWNER="oracle", GROUP="oinstall", MODE="660" KERNEL=="raw4", OWNER="oracle", GROUP="oinstall", MODE="660" KERNEL=="raw5", OWNER="oracle", GROUP="oinstall", MODE="660" "/etc/udev/rules.d/99-asm-highgo.rules" 19L, 1803C written [root@rac1 log]# start_udev Starting udev: [ OK ] [root@rac1 log]# ll /dev/raw* crw------- 1 root root 162, 0 Nov 1 12:56 /dev/rawctl /dev/raw: total 0 crw-rw---- 1 oracle oinstall 162, 1 Nov 1 14:42 raw1 crw-rw---- 1 oracle oinstall 162, 2 Nov 1 14:42 raw2 crw-rw---- 1 oracle oinstall 162, 3 Nov 1 14:42 raw3 crw-rw---- 1 oracle oinstall 162, 4 Nov 1 14:42 raw4 crw-rw---- 1 oracle oinstall 162, 5 Nov 1 14:42 raw5 crw-rw---- 1 oracle oinstall 162, 6 Nov 1 14:42 raw6 crw-rw---- 1 oracle oinstall 162, 7 Nov 1 14:42 raw7 crw-rw---- 1 oracle oinstall 162, 8 Nov 1 14:42 raw8
然后：
[root@rac1 log]# cd /u01/crs/oracle/product/10.2.0/app/bin/ [root@rac1 bin]# ./crsctl start crs Attempting to start CRS stack The CRS stack will be started shortly
可以了：
