[root@rac1 ~]# /etc/init.d/oracleasm createdisk data01 /dev/sdb1
Marking disk "data01" as an ASM disk: [FAILED][@more@]

[root@rac1 ~]# more /var/log/oracleasm

Instantiating disk: oracleasm-instantiate-disk: Unable to create ASM disk "DATA01": Permission denied
failed

出现这个需要将selinux disable掉

[root@rac1 ~]# more /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disable
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

这个需要重启才能生效，如果需要立即生效，需执行

[root@rac1 ~]# setenforce
usage: setenforce [ Enforcing | Permissive | 1 | 0 ]

[root@rac1 ~]# setenforce 0

之后便可以创建asmdisk 了。
