Re: [ClusterLabs] How to fence cluster node when SAN filesystem fail

2017-05-02 Thread Albert Weng 
Hi Klaus,

Thank you for your quickly reply.

Below is my crm_resource output :
# crm_resource --resource ora_fs -query-xml
ora_fs (ocf::heartbeat:Filesystem):Started node2.albertlab.com
xml:

  



  
  



  


I checked the document about 'on-fail' operation, you're right, my
filesystem resource behavior work correctly , it failover to another node
to 'restart' the resource. so, if i add the on-fail parameter for "move to
another node and fence the node itself" purpose as below, am i right ?

# pcs resource op remove ora_fs monitor
# pcs resource op add ora_fs monitor interval=20 timeout=40 on-fail=fence

I'm curios about why only my 'filesystem' resource will not trigger
stonith, but when 'vip' resource fail, the resource located host will be
triggered reboot immediately. (stonith : fence_ipmilan)

here is my 'ora_vip' resource output
# crm_resource --resource ora_vip --query-xml
ora_vip(ocf::heartbeat:IPaddr2):   Started node2.albertlab.com
xml:

  


  
  



  


thanks a lot.

That is the default on-fail behavior of pacemaker-operations (==restart -
either on the node itself or another node - except for stop where it is
fence).
Using the on-fail behavior fence as well for start & monitor should give
you the desired behavior as I got it from your description.

Hi,

Upstream documentation on fencing in Pacemaker is available at:

http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Pacemaker_Explained/index.html#idm139683949958512

Higher-level tools such as crm shell and pcs make it easier; see their
man pages and other documentation for details.

[ClusterLabs] How to fence cluster node when SAN filesystem fail

2017-05-01 Thread Albert Weng 
Hi All,

My environment :
(1) two node (active/passive) pacemaker cluster
(2) SAN storage attached, add resource type "filesystem"
(3) OS : RHEL 7.2

In old version of RHEL cluster, when attached SAN storage path lost(ex.
filesystem fail),
active node will trigger fence device to reboot itself.

but when i use pacemaker on RHEL cluster, when i remove fiber cable on
active node, all resources failover to passive node normally, but active
node doesn't reboot.

how to trigger fence reboot action when SAN filesystem lost?

Thank a lot~~~
