Description michal novacek 2013-08-20 12:51:58 UTC 
+++ This bug was initially created as a clone of Bug #998964 +++

Description of problem:
I do have a resource in a group haa-group-0. When issuing 'pcs resource
group remove haa-group-0' the group is removed but the resource from this group
is not deleted and remains as ungrupped resources. This is quite unexpected.

Version-Release number of selected component (if applicable):
pcs-0.9.72-1.el6.noarch

How reproducible: always

Steps to Reproduce:
1. create a group with resources using pcs
2. issue 'pcs resource group remove <group_name>'

Actual results: resource are not removed

Expected results: resources should be removed with the group

Additional info:
It would be nice to either have parameter to force resources removal and not to
do it by default or the other way round. Current behaviour is confusing.

Comment 2 Chris Feist 2013-08-26 21:29:38 UTC 
Before fix:
[root@rh7-1 test]# pcs -f /tmp/test.xml resource create A Dummy --group MyGroup
[root@rh7-1 test]# pcs -f /tmp/test.xml resource create B Dummy --group MyGroup
[root@rh7-1 test]# pcs -f /tmp/test.xml resource 
 Resource Group: MyGroup
     A	(ocf::heartbeat:Dummy):	Stopped 
     B	(ocf::heartbeat:Dummy):	Stopped 

[root@rh7-1 test]# pcs -f /tmp/test.xml resource delete MyGroup
Error: MyGroup is not a resource (it can be removed with 'resource group remove MyGroup')


After fix:
[root@ask-03 ~]# pcs -f /tmp/test.xml resource create A Dummy --group MyGroup
[root@ask-03 ~]# pcs -f /tmp/test.xml resource create B Dummy --group MyGroup
[root@ask-03 ~]# pcs -f /tmp/test.xml resource 
 Resource Group: MyGroup
     A	(ocf::heartbeat:Dummy):	Stopped 
     B	(ocf::heartbeat:Dummy):	Stopped 
[root@ask-03 ~]# pcs -f /tmp/test.xml resource delete MyGroup
Removing group: MyGroup (and all resources within group)
Deleting Resource - A
Deleting Resource (and group) - B
[root@ask-03 ~]# pcs -f /tmp/test.xml resource
NO resources configured
[root@ask-03 ~]# rpm -q pcs
