Red Hat

Hi,
I am trying to setup redhat native cluster 5, i installed all the required rpms and issued the command service cman start (cman is the cluster manager)
this gives me output...
#service cman start
Starting cluster:
Loading modules... done
Mounting configfs... done
Starting ccsd... done
Starting cman... failed
[FAILED]

It also triggers some selinux security check:
---------------------------------------------
Summary
SELinux is preventing the /usr/sbin/aisexec from using potentially
mislabeled files (tmp).

Detailed Description
SELinux has denied /usr/sbin/aisexec access to potentially mislabeled
file(s) (tmp). This means that SELinux will not allow /usr/sbin/aisexec to use these files. It is common for users to edit files in their home
directory or tmp directories and then move (mv) them to system directories. The problem is that the files end up with the wrong file context which confined applications are not allowed to access.

Allowing Access
If you want /usr/sbin/aisexec to access this files, you need to relabel them using restorecon -v tmp. You might want to relabel the entire directory using restorecon -R -v .
--------------------------------------------

I ran the commands restorecon -R -v /tmp, but it didnt solve my problem.
I would be very thankful, If you help me out...

Thanks,
Santhosh
