[root@rac2 ~]# oracleasm scandisks        
Reloading disk partitions: done
Cleaning any stale ASM disks...
Scanning system for ASM disks...
[root@rac2 ~]#

解決方法:

   是因為在rac1節(jié)點格式化磁盤沒有使用partprobe命令,分區(qū)沒有生效

在rac1執(zhí)行:

[root@rac1 ~]# partprobe

在rac2執(zhí)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"

2.安裝grid集群軟件時出現(xiàn)ORACLE_HOME和ORACLE_BASE目錄不對

錯誤提示:

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

解決方法:

我當(dāng)前目錄是:ORACLE_BASE=/home/grid

       ORACLE_HOME=/home/grid/11.2.0/grid

這樣目錄是不正確的,因為ORACLE_BASE和ORACLE_HOME目錄要分開,ORACLE_BASE安裝好后是有root權(quán)限的,而ORACLE_HOME則沒有.

這樣才對:ORACLE_BASE=/home/grid/app

      ORACLE_HOME=/home/grid/11.2.0/grid

3.在安裝grid到最后一步出錯誤,是因為scan的IP問題補(bǔ)占用了

日志:

INFO: All nodes have same "hosts" entry defined in file "/etc/nsswitch.conf"

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

INFO: ERROR:

INFO: PRVG-1101 : SCAN name "scan-cluster" failed to resolve

INFO: ERROR:

INFO: PRVF-4657 : Name resolution setup check for "scan-cluster" (IP address: 192.168.3.155) failed

INFO: ERROR:

INFO: Verification of SCAN VIP and Listener setup failed

INFO: Checking OLR integrity...

INFO: Checking OLR config file...

INFO: OLR config file check successful

INFO: Checking OLR file attributes...

INFO: OLR file check successful

解決方法:

(1).直接跳過不影響

(2),修改系統(tǒng)的nslookup二進(jìn)制文件(http://www.ithao123.cn/content-1094742.html)

4.crs無法共享磁盤通信

錯誤信息:

CRS-0184: Cannot communicate with the CRS daemon.

日志信息:

2016-09-16 09:20:48.325: [  OCRRAW][1171532096]proprdc: backend_ctx->prop_boot_mode=1

解決方法:

  這是共享磁盤的問題,我是用iscsi做的共享,查看了下asm只能掛載自己在磁盤組,將共享磁盤換成虛擬機(jī)自帶的磁盤共享就解決了.
