hi
i tried to change the IPaddr2 parameter ip

1)
crm resource edit <rsc>
 (vi .. )

2)
 pcs resource update <rsc> <attr>=<value>

in both cases the cib is modified (`crm configure show` shows)
but old ip only is pingable and all depending resources are stopped

crm resource stop p_clusterip  # does not stop that resource ?!
crm resource start p_clusterip

after
crn resource cleanup p_clusterip
i can ping both (new and old) ip

`ip addr show`
    inet 172.27.10.91/16 brd 172.27.255.255 scope global eth0
    inet 172.27.10.199/16 brd 172.27.255.255 scope global secondary eth0
    inet 172.27.10.90/16 brd 172.27.255.255 scope global secondary eth0
maybe ip_stop() / delete_address() did not succeed ?

how this is done correctly ?

thanks in advance
andreas
