Hi,<br>
<br>
Just go to
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<a href="http://clusterlabs.org/rpm/">http://clusterlabs.org/rpm/</a>
and search for the RPMs for your OS version. If you can shut the nodes
down to perform the upgrade, it would be a lot easier, if it has to be
done without downtime, that is also possible, but requires a careful
planning of what to change and when so that you don't mess up anything
and is closely related to how the cluster is set up.<br>
<br>
How I've done it was as follows:<br>
- 2 node setup, primary - secondary.<br>
- went on secondary node, put it in standby<br>
- shutdown openais<br>
- removed all cluster related RPMs (openais, pacemaker, heartbeat,
etc.) but not the drbd RPMs<br>
- installed the new RPMs, used corosync instead of openais, configured
corosync's /etc/corosync/corosync.conf based on the settings of the old
openais (actually did a meld between the old openais.conf and the new
corosync.conf and saved a unified corosync.conf)<br>
- removed everything from /var/lib/heartbeat/crm/<br>
- started corosync on secondary node<br>
- waited for node joing, then issued an standby on the primary,
everything migrated to the secondary<br>
- went on the primary, removed the RPMs, removed
/var/lib/heartbeat/crm/* configured corosync, started it<br>
<br>
Et voila, it works. BTW, awesome job done to maintain compatibility
between versions, the upgrade was truly seamless.<br>
<br>
Regards,<br>

<div class="plainMail">

<div>Thank you for your help. I want to upgrade my openais.
Do I need to restall linux and download openais of the latest version?
or any other simple way?Thanks:-). </div>

Hi,<br>
<br>
Depending on the openais version (please mention it) <br>
?<br>
Hi Thank you for your reply my openais version is openais-0.80.5-15.1<br>
pacemaker version is pacemaker-1.0.5-4.1.<br>
I use restart but it does not work.?I found?it could not stop<br>
?<br>
?<br>
this behavior could <br>
happen, I've seen it as well, on openais-0.8.0. What I've done to fix
it <br>
was to restart the openais process via /etc/init.d/openais restart. And
<br>
then it worked, however, this was one of the reasons I updated the <br>
packages to the latest versions of corosync, pacemaker, etc. The tricky
<br>
part was doing the migration procedure for upgrading production servers
<br>
without service downtime, but that's another story.<br>

Hi,<br>
<br>
Yes, it sometime needs to be killed manually because the process hangs <br>
and the restart operation never seems to end. Yet another reason to
upgrade.<br>
<br>
All,<br>
<br>
Question: given the fact that this type of software usually gets <br>
installed on a platform once and then usually goes into service for
many <br>
years, on servers where downtime should be kept to a minimum (gee, <br>
that's why you use a cluster :)), how does this fit the release
schedule?<br>
<br>
I mean, there are plenty of users out there with question related to <br>
Heartbeat 2, openais-0.8.0, and so on and so forth, some environments <br>
cannot be changed lightly, others, not at all, so what is the response <br>
to "this feature doesn't work on that version of software?", upgrade?
If <br>
so, at what interval (keeping in mind that you probably want the stable
<br>
packages on your system)?<br>
<br>
I'm asking this because when I started working with openais, the latest
<br>
version available was 0.8.0 on some SUSE repos that aren't available <br>
anymore.<br>
<br>
Regards,<br>
<br>
