标题: RHEL7.3虚拟机安装12C RAC环境执行root.sh提示ASM配置失败

RHEL7.3虚拟机安装12C RAC环境时，执行root.sh提示错误如下：

CRS-2676: Start of 'ora.cssd' on 'rac01'succeeded

ASM failed to start. Check/u01/app/grid/base/cfgtoollogs/asmca/asmca-170605PM060501.log for details.

原因：/dev/shm过小

[root@rac01 app]# df -h

tmpfs 199M 0 199M 0% /run/user/0

解决办法：
增加/dev/shm

[root@rac01 app]# umount /dev/shm

umount: /dev/shm: target is busy.

(In some cases useful info about processes that use

the device is found by lsof(8) or fuser(1))

[root@rac01 app]# fuser -km /dev/shm

/dev/shm: 27668m 27678m 27704m

[root@rac01 app]# fuser -km /dev/shm

/dev/shm: 28930m 28933m

[root@rac01 app]# fuser -km /dev/shm

/dev/shm: 28970m

[root@rac01 app]# umount /dev/shm

[root@rac01 app]# vi /etc/fstab

/*添加内容*/

tmpfs /dev/shm tmpfs defaults,size=3G

[root@rac01 app]# mount /dev/shm

[root@rac01 app]# df -h

验证：重新运行root.sh成功
