2026 Upgrade with MariaDB

[rich.anderson]

Good afternoon,

We were forced to convert our Nagios XI 2024 installation away from MySQL and over to MariaDB which is kept up to date via RHEL repositories. I went to start a nagios xi 2026 upgrade on our test system and immediately faced package conflicts with nagiosxi-nagioscore-2026r1.0.1 requiring mysql but conflicting with mariadb.

Previously mariadb was a drop in replacement with no problem. At the moment the only solution I can think of is:
Backup database
Remove mariadb
Run upgrade process
Remove mysql it installs
Reinstall mariadb
Restore database

I hope that's not the only option. I'd appreciate any input or ideas.

Thank you,
Rich

Hi Rich,

Unfortunately there is growing divergence between MySQL and MariaDB and this problem can be complicated by OS specific package dependencies. Generally speaking our recommendation is to stay with the database that was originally installed but if you want to change to MariaDB you can definitely give it a try however we may be limited in what assistance we can provide moving forward. The path you outlined sounds like it may be the best solution at this point however it will complicate future upgrades ( and we're glad to hear you have a test instance BTW ). If you do run into problems with the solution you outlined the best next step might be to open a support case so our support engineers can get a better understanding of the specifics of your install and environment; there are a number of variables that come into play with databases and upgrades.

Good Luck and have a great afternoon !!!

Good afternoon,

Well, following a different path, I did get the upgrade in place and it 'appears' successful. Web UI works, checks are running, performance graphs are generating. I do have one problem though and I'm not sure what's causing it, how to track it down, or what the problem is even doing.

The cmdsubsys.log is just repeating this:

Code: Select all

Note that when I performed an action in the Web UI it was still logged in here and processed.

Is there any additional debug I can enable to find out what is timing out?

Thank you,
Rich

Any chance someone from the Nagios support team can provide any insight?

Thank you,

Hi @rich.anderson,

If you want feedback from the support team, your best bet is to put in a support ticket. This will give you direct access to the support technicians and an SLA on the ticket. Nagios staffers and users on the forum are frequently clever, but not support technicians.

If you want more help than this forum can provide, please open a ticket with our Technical Support team at https://support.nagios.com/.
