Description Davide Brunato 2013-12-04 12:45:06 UTC

Description of problem:

"pcs" doesn't operate on the cman service. It only disables or enable pacemaker and corosync daemons. For RHEL clustering it seems better if this command acts on cman and pacemaker start-up (corosync is also activated by cman, so is better if remain disabled). 

Version-Release number of selected component (if applicable):

0.9.90-2

How reproducible:

Steps to Reproduce:
1. chkconfig --list | egrep "(corosync|pacemaker|cman)"
2. pcs cluster disable
3. chkconfig --list | egrep "(corosync|pacemaker|cman)"
4. chkconfig cman off
5. pcs cluster enable
6. chkconfig --list | egrep "(corosync|pacemaker|cman)"

Actual results:

Output of step #1:
cman           	0:off	1:off	2:on	3:on	4:on	5:on	6:off
corosync       	0:off	1:off	2:on	3:on	4:on	5:on	6:off
pacemaker      	0:off	1:off	2:on	3:on	4:on	5:on	6:off

Output of step #3:
cman           	0:off	1:off	2:on	3:on	4:on	5:on	6:off
corosync       	0:off	1:off	2:off	3:off	4:off	5:off	6:off
pacemaker      	0:off	1:off	2:off	3:off	4:off	5:off	6:off

Output of step #6:
cman           	0:off	1:off	2:off	3:off	4:off	5:off	6:off
corosync       	0:off	1:off	2:on	3:on	4:on	5:on	6:off
pacemaker      	0:off	1:off	2:on	3:on	4:on	5:on	6:off

Expected results:

Output of step #1:
cman           	0:off	1:off	2:on	3:on	4:on	5:on	6:off
corosync       	0:off	1:off	2:on	3:on	4:on	5:on	6:off
pacemaker      	0:off	1:off	2:on	3:on	4:on	5:on	6:off

Output of step #3:
cman           	0:off	1:off	2:off	3:off	4:off	5:off	6:off 
corosync       	0:off	1:off	2:off	3:off	4:off	5:off	6:off
pacemaker      	0:off	1:off	2:off	3:off	4:off	5:off	6:off

Output of step #6:
cman           	0:off	1:off	2:on	3:on	4:on	5:on	6:off
corosync       	0:off	1:off	2:off	3:off	4:off	5:off	6:off
pacemaker      	0:off	1:off	2:on	3:on	4:on	5:on	6:off

Additional info:

Maybe is sufficient correct the file:

/usr/lib/python2.6/site-packages/pcs/utils.py 

using the call "utils.is_rhel6" into the functions utils.enableServices() and utils.disableServices().

Before Fix:  (enables corosync *and* pacemaker)

[root@bid-05 ~]# rpm -q pcs
pcs-0.9.121-1.el6.x86_64
[root@bid-05 ~]# chkconfig --list | grep 'cman\|corosync\|pacemaker'
cman           	0:off	1:off	2:off	3:off	4:off	5:off	6:off
corosync       	0:off	1:off	2:off	3:off	4:off	5:off	6:off
pacemaker      	0:off	1:off	2:off	3:off	4:off	5:off	6:off
[root@bid-05 ~]# pcs cluster enable
[root@bid-05 ~]# chkconfig --list | grep 'cman\|corosync\|pacemaker'
cman           	0:off	1:off	2:off	3:off	4:off	5:off	6:off
corosync       	0:off	1:off	2:on	3:on	4:on	5:on	6:off
pacemaker      	0:off	1:off	2:on	3:on	4:on	5:on	6:off
[root@bid-05 ~]# pcs cluster disable
[root@bid-05 ~]# chkconfig --list | grep 'cman\|corosync\|pacemaker'
cman           	0:off	1:off	2:off	3:off	4:off	5:off	6:off
corosync       	0:off	1:off	2:off	3:off	4:off	5:off	6:off
pacemaker      	0:off	1:off	2:off	3:off	4:off	5:off	6:off


After Fix: (only enables pacemaker)

[root@bid-05 ~]# rpm -q pcs
pcs-0.9.122-4.el6.x86_64
[root@bid-05 ~]# chkconfig --list | grep 'cman\|corosync\|pacemaker'
cman           	0:off	1:off	2:off	3:off	4:off	5:off	6:off
corosync       	0:off	1:off	2:off	3:off	4:off	5:off	6:off
pacemaker      	0:off	1:off	2:off	3:off	4:off	5:off	6:off
[root@bid-05 ~]# pcs cluster enable
[root@bid-05 ~]# chkconfig --list | grep 'cman\|corosync\|pacemaker'
cman           	0:off	1:off	2:off	3:off	4:off	5:off	6:off
corosync       	0:off	1:off	2:off	3:off	4:off	5:off	6:off
pacemaker      	0:off	1:off	2:on	3:on	4:on	5:on	6:off
[root@bid-05 ~]# pcs cluster disable
[root@bid-05 ~]# chkconfig --list | grep 'cman\|corosync\|pacemaker'
cman           	0:off	1:off	2:off	3:off	4:off	5:off	6:off
corosync       	0:off	1:off	2:off	3:off	4:off	5:off	6:off
pacemaker      	0:off	1:off	2:off	3:off	4:off	5:off	6:off
