解决办法：查看oracleasmlib库文件是否存在[root@t_rac_one:~]# rpm -ql oracleasmlib-2.0.4-1.SLE10/opt/oracle/extapi/opt/oracle/extapi/64/opt/oracle/extapi/64/asm/opt/oracle/extapi/64/asm/orcl/opt/oracle/extapi/64/asm/orcl/1/opt/oracle/extapi/64/asm/orcl/1/libasm.so/usr/sbin/oracleasm-discover[root@t_rac_one:/]# cd /opt/oracle[root@t_rac_one:/opt/oracle]# lsbin发现这些文件己丢失或被意外删除，因此需要重新安装。[root@t_rac_one:~]# rpm -qa | grep -i oracleasmliboracleasmlib-2.0.4-1.SLE10[root@t_rac_one:~]# rpm -e oracleasmlib-2.0.4-1.SLE10清除残留的目录结构[root@t_rac_one:/opt]# rm -rf oracle/[root@t_rac_one:~]# rpm -ivh oracleasmlib-2.0.4-1.sle10.x86_64.rpmPreparing... ########################################### [100%] 1:oracleasmlib ########################################### [100%][root@t_rac_one:/opt/oracle]# ls -ltotal 0drwxr-x--- 2 root 507 80 2011-06-23 23:26 bindrwxr-xr-x 3 root root 72 2011-07-06 04:31 extapi重新配置oracleasm,配置完后重启oraclasm或scandisks[root@t_rac_one:/opt/oracle]# /etc/init.d/oracleasm configureConfiguring the Oracle ASM library driver.This will configure the on-boot properties of the Oracle ASM librarydriver.
