Hi William,
Here is some notes on upgrades using OMD, which might help. (summarized
from our internal docs. Make sure you have backups before you follow any
of this. It worked for us.)
Oh, and repo we are using is:
rpm -Uvh
https://labs.consol.de/repo/stable/rhel6/x86_64/labs-consol-stable.rhel6.noarch.rpm
*
*BROKEN UPDATES* are the biggest problem with the *OMD*
distribution**. Automatic updates are, for all intents & purposes,
broken. Please insert more colorful language and looks of confusion.
Here is the first hint that there might be an issue:
[root@ ~]# yum check-update
Loaded plugins: refresh-packagekit, rhnplugin, security
This system is receiving updates from RHN Classic or RHN Satellite.
Notice the lack of telling you there is an update for |omd|. Then to
double check, running this:
[root@ ~]# yum list omd*
...<snip>...
Installed Packages
omd-1.20.x86_64 rh61-33 @labs_consol_stable
Available Packages
omd-1.30.x86_64 el6-35
labs_consol_stable
(red means orphaned files) These things normally should be installed
automatically, but for unknown reason(s), the *OMD* maintainers have
included the version into the name. (poor understanding of rpm's?)
*
*MISSING FILES*: updating from OMD 1.20 to 1.30 the graphing
component was broken. The libdbi.so.0 library was missing from the
OMD rpm, crucial for the graphing component. The omd-1.30.x86_64 rpm
also did not catch this as a dependency.
1.
To locate rpm for the missing file we used the following command:
yum whatprovides "*/libdbi.so.0"
2.
Installed the following package:
yum install libdbi-0.8.3-3.1.el6.x86_64
* *FORCED UPDATES*: updating (assuming just a "production" site)
1. Stop your site(s):
omd stop prod
2.
Create a copy of the prod site to run the upgrade against the
copy first. Make sure to *always keep a copy of the old version*
in case it needs to be reverted:
omd cp prod <new site name>
3. Check for current installed packages and available packages:
yum list omd*
4. Check for omd versions of of old and new site:
omd sites
5. Start new copied site and verify it's up and running:
omd start <new site name>
6. Stop the new site:
omd stop <new site name>
7. Force the 'update':
yum install omd -y
8. Update new site with the |omd update| command:
omd update <new site name>
9. You may receive an message stating 'Non empty obsolete directory
va/nagvis/userfiles. The directory var/nagvis/userfiles has
become obsolete in the new version….'. Use *d* to delete that
directory.
10. Start the newly updated site:
omd start <new site name>
11. Once the new copied site is tested and everything works well go
ahead and run through the steps for the production site, then
delete the test copy. If there are issues with the new version
and would like to revert back to the old version follow the
“*Reverse OMD Upgrade*” process. (delete the copied site, and
use yum to revert the omd install you did. "yum history undo <id>"

I have to admit. I kept going to http://omdistro.org/ only.
There's omd 2.1? I can't find the package and I don't see version
update/history.

Hi William,
Once you get the newer package installed you can do the update. The
omd versions install side by side and then you upgrade your site
between versions.
Sounds like getting the appropriate repo configured and then searching
for the new version to install with your package manager will allow
you to get the "omd upgrade site" to migrate to the newest version.

I ran `omd update <site>` and it returns nothing.
I sure don't have that repo. I'll look into this. Thanks.

To be fair you links to the 1.30 version are not on the
omdistro.org <http://omdistro.org> site. The only indication
there is the changelog.
e.g. http://files.omdistro.org/releases/centos_rhel/
I would assume the repositories are up to date though?

HI
I've been using OMD 1.20 for the past few months. I like
it as a full setup of packages without the need to fixing
config for each little components. However I see that
there's not much update. May I ask if there's any plan
continue the development?
Another question is whether it is possible to update
Check_mk only with my OMD setup?

William Kwan
