[ClusterLabs] [Problem] Thel fail-over is completed without the stop of the resource being carried out.

2016-09-26 Thread renayama19661014

Hi All,

We discovered a problem in the cluster which Quorum control and STONITH did not 
have.

We can confirm the problem in the next procedure.

Step1) Constitute a cluster.

[root@rh72-01 ~]# crm configure load update trac3437.crm 

[root@rh72-01 ~]# crm_mon -1 -Af
Stack: corosync
Current DC: rh72-01 (version 1.1.15-e174ec8) - partition with quorum
Last updated: Mon Sep 26 13:00:22 2016  Last change: Mon Sep 26 
12:59:52 2016 by root via cibadmin on rh72-01

2 nodes and 1 resource configured

Online: [ rh72-01 rh72-02 ]

Resource Group: grpDummy
prmDummy   (ocf::pacemaker:Dummy): Started rh72-01

Node Attributes:
* Node rh72-01:
* Node rh72-02:

Migration Summary:
* Node rh72-01:
* Node rh72-02:


Step2) Edit Dummy resource to cause stop trouble.

(snip)
dummy_stop() {
return $OCF_ERR_GENERIC
dummy_monitorif [ $? -eq $OCF_SUCCESS ]; thenrm ${OCF_RESKEY_state} 
   fi
rm -f "${VERIFY_SERIALIZED_FILE}"
return $OCF_SUCCESS
}
(snip)

Step3) Stop Pacemaker of the node. Stop trouble happens.
[root@rh72-01 ~]# systemctl stop pacemaker

[root@rh72-01 ~]# crm_mon -1 -Af
Stack: corosync
Current DC: rh72-01 (version 1.1.15-e174ec8) - partition with quorum
Last updated: Mon Sep 26 13:01:33 2016  Last change: Mon Sep 26 
12:59:52 2016 by root via cibadmin on rh72-01

2 nodes and 1 resource configured

Online: [ rh72-01 rh72-02 ]

Resource Group: grpDummy
prmDummy   (ocf::pacemaker:Dummy): FAILED rh72-01 (blocked)

Node Attributes:
* Node rh72-01:
* Node rh72-02:

Migration Summary:
* Node rh72-01:
prmDummy: migration-threshold=1 fail-count=100 last-failure='Mon Sep 26 
13:01:18 2016'
* Node rh72-02:

Failed Actions:
* prmDummy_stop_0 on rh72-01 'unknown error' (1): call=8, status=complete, 
exitreason='none',
last-rc-change='Mon Sep 26 13:01:18 2016', queued=0ms, exec=33ms

Step4) Correct Dummy resource in the original.
(snip)
dummy_stop() {
dummy_monitor
if [ $? -eq $OCF_SUCCESS ]; then
rm ${OCF_RESKEY_state}
fi
rm -f "${VERIFY_SERIALIZED_FILE}"
return $OCF_SUCCESS
}
(snip)

Step5) Clean up does the trouble of the Dummy resource.

[root@rh72-01 ~]# crm_resource -C -r prmDummy -H rh72-01 -f
Cleaning up prmDummy on rh72-01, removing fail-count-prmDummy
Waiting for 1 replies from the CRMd. OK

Step6) Fail-over is completed. However, the stop of the Dummy resource is not 
carried out in rh72-01 node.

[root@rh72-02 ~]# crm_mon -1 -Af
Stack: corosync
Current DC: rh72-02 (version 1.1.15-e174ec8) - partition WITHOUT quorum

Yes, DBus would be one of the ways.

Thank you,

There is no direct-API or so just the Agent-Interface.
But of course the Agent can be a binary compiled from c++ code
that communicates via some IPC with whoever.

Where you thinking of e.g. a DBus interface?

Correcting a typo.
* the same -> I also was hoping to hear that I can do the same from c++
code.

Thanks for the answer.

I also was hoping to hear that I can do the case from c++ code.

Sounds like a use case for the alerts-feature coming with pacemaker-1.1.15.
You can configure alert-agents to be called in the cases mentioned.
Meanwhile there should be high-level-tooling support from crmsh & pcs.
Legacy features for a similar purpose are ClusterMon-RA & cluster-properties
notification-agent/recipient.
