</div>If you are working on SLE11, please use the pacemaker list only. These<br>

<br>
</div>openAIS doesn't support any resource agents, those come from other<br>
packages. But in your installed system, simply look at<br>
/usr/lib/ocf/resource.d/<br>
<br>
This will also be documented in the Novell provided product docs, of<br>
course.<br>
<div class="Ih2E3d"></div></blockquote><div><br> i had no idea that openAIS doesnot support RA. can you send me the link of novell doc , i may get some other useful information also. <br><br>i saw that dir and found heatbeat, lvm2 , ocfs2 and pacemaker there.<br>
now one question if i want to use any of these RA in openAIS cluster can i use heatbeat , lvm2 ,ocfs2 or pacemaker's RA by making them provider.<br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<br>
</div>There is a scsi_reservation resource agent, but it is not used for<br>
node-level fencing; you can simply add it to the resource hierarchy as<br>
required.<br>
<br>
If you want to fence through shared storage, the external/sbd stonith<br>
script might be want you want.<br>

<br>
</div>You can simply specify the network address, no need to specify the<br>
explicit IP address here. (ie, likely 192.168.2.0).<br>
<br>
And if you want to use OCFS2, you must specify an explicit nodeid: field<br>
(1, 2, 3, 4, ... this needs to be unique on each node).<br>

<br>
</div>You NEVER edit cib.xml manually. _Never_. Only through tools such as<br>
hb_gui, the "crm" shell, cibadmin etc.<br>
<br>
You don't need to add nodes to the configuration explicitly, they'll get<br>
auto-added to the CIB as soon as openais forms a ring. Try without<br>
"secauth", maybe the encryption is proving troublesome for you.<br>
<br>
There are docs on <a href="http://clusterlabs.org" target="_blank">clusterlabs.org</a> on how to set this all up, too.<br>
<br>
<br>
