It is said that the kernel version is wrong with the installed oracleasm version.

Check the version

[Root @ rac1 ~] # Rpm-qa | grep oracleasm
Oracleasm-support-2.1.7-1.el4
Oracleasm-2.6.9-42.EL-2.0.3-1
Oracleasmlib-2.0.4-1.el4
[Root @ rac1 ~] # Uname-r
2.6.9-89.EL
[Root @ rac1 ~] #
Obviously, the oracleasm version is incorrect.

Download it from the official website. Each version has the corresponding oracleasm version.
