Hello,<br>
<br>
I'm trying to configure a cluster based in pacemaker and corosync in two ubuntu precise servers. The cluster is for an active/standby pop/imap server with a shared storage accesed through fibrechannel.<br>
<br>
In order to avoid concurrent access to this shared storage, I need clvm (maybe I'm wrong), so I'm trying to configure it. According to different guides and howtos I have found I have configured a DLM and clvm resource:<br>
<br>
root@myotis51:/etc/cluster# crm configure show<br>
node myotis51<br>
node myotis52<br>
primitive clvm ocf:lvm2:clvmd \<br>
params daemon_timeout="30" \<br>
meta target-role="Started"<br>
primitive dlm ocf:pacemaker:controld \<br>
meta target-role="Started"<br>
group dlm-clvm dlm clvm<br>
clone dlm-clvm-clone dlm-clvm \<br>
meta interleave="true" ordered="true"<br>
property $id="cib-bootstrap-options" \<br>
dc-version="1.1.6-<u></u>9971ebba4494012a93c03b40a2c58e<u></u>c0eb60f50c" \<br>
cluster-infrastructure="cman" \<br>
expected-quorum-votes="2" \<br>
stonith-enabled="false" \<br>
no-quorum-policy="ignore" \<br>
last-lrm-refresh="1363957949"<br>
rsc_defaults $id="rsc-options" \<br>
resource-stickiness="100"<br>
<br>
With this configuration, resources are not launched, I think because DLM is failing because it's trying to launch dlm_controld.pcmk which is not installed in my system<br>

<br>
The problem with this is that I can't find any dlm_controld.pcmk binary for ubuntu. Any idea on how to fix this?<br>
<br>
The closest command I have found is dlm_controld provided with cman packages, but then I have to replace corosync with cman. Doing this is not a big problem for me. The fact is that I'm newbie in HA and the use of corosync instead of cman is because this is the one documented with pacemaker (<a href="http://clusterlabs.org/doc/en-US/Pacemaker/1.1-plugin/html/Clusters_from_Scratch/index.html" target="_blank">http://clusterlabs.org/doc/<u></u>en-US/Pacemaker/1.1-plugin/<u></u>html/Clusters_from_Scratch/<u></u>index.html</a>).<br>
<br>
Is it corosync supposed to be better (or more open or more standard based) than cman? In case corosync is more recommended, then what is the solution for the dlm problem?<br>
<br>
Thanks in advanced.<br>
