Hello,
<br>
<br>
disclaimer: I have posted this issue to linux-ha list too a couple
of days ago. I'm sorry if this is not the correct list, and thanks
if you can give me a hint about which cluster stack should I use for
ocfs2 by now.<br>
<br>
I'm trying to compile all stack for corosync + pacemaker + dlm +
ocfs2 (with dlm_controld.pmk), without cman stack. I'm following the
"From source" Pacemaker guide.<br>
<br>
After some days trying to compile the correct combination of
sources/versions, I have no success, and I'm not sure if at this
moment this is possible.<br>
<br>
The fist problem was that cluster removed support for dlm_controld
with pacemaker stack. Last version with support was 3.0.17.
<br>
But this was done some years ago, and as far as I have been able to
understand, things are still broken.
<br>
<br>
<br>
The most relevant info found about this issue are these threads from
Andrew Beekhof and Vladislav Bogdanov, wich suggest to compile
dlm_controld from Cluster, applying some patches. They report it
worked (whith some remaining issues):

<br>
<br>
But most recent issue about this is a year ago, and seems that
things are still broken.
<br>
I haven't been able to compile, with lots of errors, so I'm
currently asking if this is the right way, becouse seems that nobody
else is willing to use this...
<br>
<br>
<br>
At cluster page, they state that now DLM code has been separated
from cluster:
<br>

href="https://fedorahosted.org/cluster/wiki/HomePage">https://fedorahosted.org/cluster/wiki/HomePage</a>
<br>
<br>
But this dlm project (that seems to have pcmk support), depends on
corosync 2.0, so it can't run with last pacemaker (1.1.8). (can it?)
<br>
<a class="moz-txt-link-freetext"
href="http://git.fedorahosted.org/git/dlm.git">http://git.fedorahosted.org/git/dlm.git</a>
<br>
<br>
Before spending more time with this, I wanted to ask for the right
way to do things.
<br>
So Questions are:
<br>
<br>
(1) Is it by now possible to get an ocfs2 corosync + pacemaker
cluster, without cman, and dlm_controld with pcmk stack? (if yes
which repos/versions)?
<br>
(2) What is the future roadmap about this? Will future corosync2.0
cluster have dlm issues addressed?
<br>
<br>
Also, I have read (also Andrew post) that OCFS2 cluster could have
problems on top of corosync 2.0, as OCFS2 has't ben ported (GFS2 was
ported).
<br>

href="http://www.gossamer-threads.com/lists/linuxha/pacemaker/78538">http://www.gossamer-threads.com/lists/linuxha/pacemaker/78538</a>
<br>
so:
<br>
(3) Is GSF2 a better future option in terms of support, for linux-ha
clusters?
<br>
<br>
<br>
More details about pcmk dlm_controld:
<br>
I found that Suse have always been mantaining cman-free cluster
stack, so I have tried to find dlm in its packages.
<br>
Found:
<br>
<a class="moz-txt-link-freetext"
href="http://rpmfind.net//linux/RPM/opensuse/factory/x86_64/libdlm-3.00.01-24.5.x86_64.html">http://rpmfind.net//linux/RPM/opensuse/factory/x86_64/libdlm-3.00.01-24.5.x86_64.html</a>
<br>
<br>
But also I have had lots of compilation problems, trying several
pacemaker, versions, also the suse-patched ones. Haven't been able
to successfully complie a dlm_controld.<br>
<br>
<br>
Thanks and Regards,
<br>
Bernardo
