本文记录了一次10g RAC集群重启后无法正常启动的问题排查过程。通过查看系统日志发现集群资源服务等待依赖项的问题，并进一步定位到投票盘权限设置错误。修改权限后成功解决了启动故障。

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--- 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 14:37:24 rac1 logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.2826.

有戏！

[root@rac1 log]# vi  /tmp/crsctl.2826

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

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：

[oracle@rac1 bdump]$ crs_stat -t -v
