在安裝ORACLE RAC的Grid Infrastructure時，在節點1運行/u01/app/11.2.0/grid/root.sh正常，當在節點2運行/u01/app/11.2.0/grid/root.sh時發生報錯：

根據上面報錯，可以看到是因為在啟動ora.asm磁盤時發生了錯誤，因此對比兩個節點的asm磁盤權限，發現以下問題：
節點1：
[root@RAC01 app]# ls -l /dev/asm* brw-rw---- 1 oracle oinstall 8, 16 Feb 6 05:26 /dev/asm-disk1 brw-rw---- 1 oracle oinstall 8, 32 Feb 6 05:26 /dev/asm-disk2 brw-rw---- 1 oracle oinstall 8, 48 Feb 6 05:26 /dev/asm-disk3 brw-rw---- 1 oracle oinstall 8, 64 Feb 6 02:59 /dev/asm-disk4
節點2：
[root@RAC02 app]# ls -l /dev/asm* brw-rw----. 1 oracle oinstall 8, 16 Feb 6 05:26 /dev/asm-disk1 brw-rw----. 1 oracle oinstall 8, 32 Feb 6 05:26 /dev/asm-disk2 brw-rw----. 1 oracle oinstall 8, 48 Feb 6 05:26 /dev/asm-disk3 brw-rw----. 1 oracle oinstall 8, 64 Feb 6 02:59 /dev/asm-disk4
從上面可以看到節點2的asm磁盤權限中多了一個‘.’，這里的點是seLinux的附件權限，但是查看seLinux已經處於Premissive，配置文件中已修改為disabled，因此重啟服務器，再次查看asm權限，發現‘.’消失，再次執行/u01/app/11.2.0/grid/root.sh腳本，無報錯
