2. 采用RHEL6.5 multipath多路徑軟件安裝采用ASMLIB方式配置ASM共享磁盤成功,但是在第二節(jié)點(diǎn)執(zhí) 行root.sh報(bào)如下錯(cuò)誤提示,解決方式見3.
Disk Group CRS creation failed with the following message:
ORA-15018: diskgroup cannot be created
ORA-15072: command requires at least 1 regular failure groups, discovered only 0

see asmca logs at /u01/app/grid/cfgtoollogs/asmca for details
Did not succssfully configure and start ASM at /u01/app/11.2.0/grid/crs/install/crsconfig_lib.pm line 6912.

node1,node2 下:
# vi /etc/sysconfig/oracleasm
ORACLEASM_ENABLED=true
ORACLEASM_UID=grid
ORACLEASM_GID=asmdba
ORACLEASM_SCANBOOT=true
ORACLEASM_SCANORDER="dm"
ORACLEASM_SCANEXCLUDE="sd"
ORACLEASM_USE_LOGICAL_BLOCK_SIZE=false
# /etc/init.d/oracleasm restart
第二節(jié)點(diǎn)先執(zhí)行清除配置,再執(zhí)行root.sh即可:
# /u01/app/11.2.0/grid/crs/install/roothas.pl -delete -force -verbose
# /u01/app/11.2.0/grid/root.sh
