[Pacemaker] error installing CentOS clvm after using clusterlabs repository

[Michael Fung]

Thanks Brett.


I tried the clvm package and found it still requires the RHCS stuff,
ARGH!!! It seems I must either study the RHCS stuff or compile a clvm
package that use corosync/openais. I feel depressed.


Rgds,
Michael
