原文地址:RAC故障处理一例 作者:itpub.com.cn

上周六午夜12点刚要睡觉,电话响起,这个时候来电话肯定没啥好事,一看手机号码不认识,通了电话才知道是我们外聘的HP工程师在客户现场处理故障,客户是两台HP小型机做了一个两个节点的RAC,由于客户的原因导致第二个节点系统无法进入多用户模式,估计是在系统里乱操作,删了什么操作系统文件,导致机器只能进入维护模式,因此第二个节点不得不重新安装,HP工程师是克隆了另外一个节点的系统到第二个节点的,然后修改IP,主机名等等的配置好Service Guard后,HA能起来,但是启动CRS的时候,第二个节点报如下错误:

  1. Attempting to start CRS stack
  2. Failure at scls_scr_create with code 1
  3. Internal Error Information:
  4.   Category: 1234
  5.   Operation: scls_scr_create
  6.   Location: mkdir
  7.   Other: Unable to make user dir
  8.   Dep: 2
折腾了半天毫无进展,想重启系统然系统自己带起来,但是跟HP的工程师交流了一下,主机起来后CRS是要手工启动的,那么重启就毫无意义了,在Unix、Linux下,CRS的启动停止脚本是放在init.d目录里的,对HP-Unix不太熟悉,问了才知道HP-Unix中,这个目录是在/sbin/init.d 中,而不是/etc/init.d 目录,从这个目录里用./init.crs 脚本来启动CRS,用法如下:
# ./init.crs xxx <--随便输入一个让它显示用法
Usage: ./init.crs {stop|start|enable|disable}
# ./init.crs start
这次的错误信息有参考意义了:

  1. /sbin/init.d/init.cssd[537]: /var/opt/oracle/scls_scr/rqtmsdb2/root/cssrun: Cannot create the specified file.
  2. Startup will be queued to init within 30 seconds.
错误日志显示CRS不能创建cssrun这个文件,
检查之:
# cd /var/opt/oracle/scls_scr/rqtmsdb2/root/
sh: /var/opt/oracle/scls_scr/rqtmsdb2/root/:  not found.
咦,没有这个目录!
#
cd /var/opt/oracle/scls_scr/
ls -l 一看就明白了:

  1. # ls -l
  2. total 0
  3. drwxr-xr-x 4 root sys 96 Dec 31 2010 rqtmsdb1
因为这个系统是从第一个节点克隆过来的,所以这个本应该是rqtmsdb2的目录现在是rqtmsdb1,怪不得呢!
修改之:

  1. # mv rqtmsdb1 rqtmsdb2
  2. # ls -l
  3. total 0
  4. drwxr-xr-x 4 root sys 96 Dec 31 2010 rqtmsdb2
  5. # cd rq*
    # ls -l
    total 16

    # cd root
    # ls -l
    total 48

这次能够正常启动了!
回头检查第一个节点,这个节点HP工程师跟我说什么也没动过,我就信了,克隆一个系统嘛是对这个节点不用做任何改动,但是现实且很残酷!
命令敲下去:
#
cd /sbin/init.d

#

#
./init.crs start
Startup will be queued to init within 30 seconds.
等不到d.bin的进程,无任何反应,回头检查操作系统日志:

  1. Nov 18 03:26:00 rqtmsdb1 syslog: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.2104.
  2. Nov 18 03:26:00 rqtmsdb1 syslog: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.2116.
  3. Nov 18 03:26:00 rqtmsdb1 syslog: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.2154.
  4. Nov 18 03:34:16 rqtmsdb1 syslog: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.2154.
看来有些错误信息啊,其中的一个文件:

  1. #cat /tmp/crsctl.2104
  2. Failed 3 to bind listening endpoint:(ADDRESS=(PROTOCOL=tcp)(HOST=rqtmsdb1-priv))
  3. #
无法绑定监听到PricateIP上,再去检查/etc/hosts文件,发现没有Pricate IP!,只有第二个节点的Pricate IP,再去检查第二个节点的/etc/hosts文件,对比后添加第一个节点的Pricate IP :
192.168.0.1     rqtmsdb1-priv
没在开始去检查/etc/hosts文件真是失误啊!听到的一定要自己再确认一遍!又一次在RAC环境里载在/etc/hosts文件手里!!!之前在一个客户那里配置RAC,工程师给我将localhosts这个系统默认的东东去掉了,导致我在这个上面花了一天的时间才找到是没有localhosts导致的!
再次启动CRS,这次正常启动了!以为一切都好了,可以去睡觉了,没先到后面VIP还有问题,
crs_start -all  启动Cluste,报告不能启动,VIP起不来,后面的就都失败了,这个错误好办,之前解决过,先设置对VIP进行debug:

  1. #/ora_soft/oracle/product/crs/bin/crsctl debug log res "ora.rqtmsdb1.vip:5"
然后单独启动VIP资源:

  1. # /ora_soft/oracle/product/crs/bin/srvctl start nodeapps -n rqtmsdb1

没有配置默认网关,在检查IP地址配置情况,发现,IP地址是配置在lan2上的,一问才知道,由于lan0经常出问题,这次改到lan2,不早说啊,nnd!!

VIP在启动的时候回去ping默认网关,如果不通,那么VIP是起不来的。HP工程师配置好默认网关后,修改VIP到lan0上去:
先删除之:
su - oracle
oifcfg delif -global
然后再重新配置:

  1. $oifcfg setif -global lan2/172.16.7.0:public
  2. $oifcfg setif -global lan3/192.168.0.0:cluster_interconnect

#/ora_soft/oracle/product/crs/bin/srvctl modify nodeapps -n rqtmsdb2 -A 172.16.7.23/255.255.255.0/lan2

#/ora_soft/oracle/product/crs/bin/srvctl modify nodeapps -n rqtmsdb1 -A 172.16.7.22/255.255.255.0/lan2

修改完成后再次crs_start -all ,RAC启动成功,手工,睡觉!
