runcluvfy.sh result: Check for ASMLib configuration failed

I'm trying upgrade 11.1.0.7.0 to 11.2.0.3 on linux.

runcluvfy.sh gives result as this:

==================================================================

Checking ASMLib configuration.
  Node Name                             Status
  ------------------------------------  ------------------------
  node1                             (failed) ASMLib configuration is incorrect.
  node2                             (failed) ASMLib configuration is incorrect.
Result: Check for ASMLib configuration failed.

===================================================================

here are some asm related:

==========================

/etc/init.d/oracleasm listdisks
DISK02

/usr/sbin/oracleasm configure
ORACLEASM_ENABLED=true
ORACLEASM_UID=oracle
ORACLEASM_GID=oinstall
ORACLEASM_SCANBOOT=true
ORACLEASM_SCANORDER=""
ORACLEASM_SCANEXCLUDE=""

/etc/init.d/oracleasm status
Checking if ASM is loaded: yes
Checking if /dev/oracleasm is mounted: yes

Current two nodes RAC,ASM work fine.

Can some one give hint what I should check about asm?
