1.在rac2节点使用oracleasm找不到共享磁盘
[root@rac2 ~]# oracleasm scandisks
Reloading disk partitions: done Cleaning any stale ASM disks... Scanning system for ASM disks... [root@rac2 ~]#解决方法:
是因为在rac1节点格式化磁盘没有使用partprobe命令,分区没有生效
在rac1执行:
[root@rac1 ~]# partprobe
在rac2执行:[root@rac2 ~]# /usr/sbin/oracleasm scandisks
Reloading disk partitions: done Cleaning any stale ASM disks... Scanning system for ASM disks... Instantiating disk "VOL04" Instantiating disk "VOL03" Instantiating disk "VOL01" Instantiating disk "VOL02" [root@rac2 ~]# /usr/sbin/oracleasm listdisks VOL01 VOL02 VOL03 VOL04 [root@rac2 ~]#2.安装grid集群软件时出现ORACLE_HOME和ORACLE_BASE目录不对
错误提示:
INS-32026]The Software Location specified should not be under Oracle base location.
CAUSE: Grid Infrastructure for a Cluster installation will assign root ownership to all parent directories of clusterware software location. As a result, all named directories in the software location path will acquire root ownership. This may create problems for subsequent installations into the same Oracle base. ACTION: Specify software location outside of Oracle base解决方法:
我当前目录是:ORACLE_BASE=/home/grid
ORACLE_HOME=/home/grid/11.2.0/grid
这样目录是不正确的,因为ORACLE_BASE和ORACLE_HOME目录要分开,ORACLE_BASE安装好后是有root权限的,而ORACLE_HOME则没有.
这样才对:ORACLE_BASE=/home/grid/app
ORACLE_HOME=/home/grid/11.2.0/grid
3.在安装grid到最后一步出错误,是因为scan的IP问题补占用了
日志:

INFO: Check for integrity of name service switch configuration file "/etc/nsswitch.conf" passed

解决方法:
(1).直接跳过不影响
(2),修改系统的nslookup二进制文件(
4.crs无法共享磁盘通信
错误信息:
CRS-0184: Cannot communicate with the CRS daemon.

解决方法:
这是共享磁盘的问题,我是用iscsi做的共享,查看了下asm只能挂载自己在磁盘组,将共享磁盘换成虚拟机自带的磁盘共享就解决了.
