init.cssd startcheck—HP Service Guard未启动导致CRS无法正常启动

发表于 2015 年 5 月 25 日由惜分飞

早上到客户现场,客户告知有一套环境替换OCR和VOTEDISK之后,crs无法启动,让我看看。环境:HP RAC(只用一个节点)+10.2.0.5 Oracle 数据库
start crs显示正常,但是无法启动

# /app/oracle/product/10.2.0/crs/bin/crsctl start crs
Attempting to start CRS stack 
The CRS stack will be started shortly

# ps -ef|grep crs
    root  6461     1  0  May 19  ?         0:00 /bin/sh /sbin/init.d/init.crsd run
    root 29719 23678  0 10:04:51 pts/tc    0:00 grep crs

也无任何日志

表决磁盘和OCR信息

[xifenfei01][orawj][/root/xifenfei]#ocrcheck

located 3 votedisk(s).

这里可以看出来表决磁盘和ocr等相关信息正常

显示init.cssd startcheck进程

  oracle 20534 11033  0 11:30:35 pts/ta    0:00 grep init

这里的init.cssd startcheck大部分情况下，是由于不能访问存储或者第三方集群件无法访问导致

这里可以看到，三个存放表决磁盘和ocr的vg都是available的

看votedisk和ocr权限

# ls -l /dev/vgc0*/rCMPR*|grep -v .dbf|grep -v .log|grep -v .ctl
crw-r-----   1 oracle     dba         64 0x020008 May 24 14:40 /dev/vgc01/rCMPR_VGC01_OCR1

直接修改权限为777,然后尝试

# chmod 777 /dev/vgc0*/rCMPR*|grep -v .dbf|grep -v .log|grep -v .ctl
#  ls -l /dev/vgc0*/rCMPR*|grep -v .dbf|grep -v .log|grep -v .ctl

证明修改lv权限,问题依旧,不是votedisk和ocr的权限和所有者导致,通过dd和strings读相关文件，发现都OK.

这里可以通过-x调试shell脚本，发现crs在等待HP-UX Service Guard启动,从而可以确定是由于HP-UX Service Guard未启动

检查HP-UX Service Guard是否启动

通过这里,结合客户描述(只启动了一个节点，另外一个节点的vg未激活)，可以判断出来由于只使用一个节点,在未启动Service Guard的情况下,直接激活vg,由于Service Guard未启动导致crs无法启动
