Re: MariaDB server horribly slow on start


AH! Thanks for the input about PMM, I'm actually using netdata as you can see on screenshot.

And yes, it's better to have one than nothing, it helped me numerous times spot improvements and limits that could be changed to improve things.

I did an upgrade from 10.4 -> 10.5 -> 10.6 while it kept saying SST are not supported, but it worked 😉 Not sure I'm glad it worked now that I might have to revert back to 10.4 (and Ubuntu 20.04!).

I prefer v1, but in Percona's build of PMM v1 there are several bugs / missing features that are going to cause you problems with newer kernels and MariaDB 10.5+.

I have patches to fix it, but my build of it is not yet publicly available. But v2 is still far better than no PMM.

I cannot say I have looked. I'm generally happy to leave testing to others until I have an overwhelming reason to upgrade to a version with a lot of changes. And 10.5 was a rather big feature release.

Replication from newer version to older version is also not officially supported. It usually works, though.
