maxscale cannot find gtid_binlog_pos

Asked 2021-Apr-09 at 17:15

I have active master - slave (ssl) replication. I installed maxscale, set a configuration, but maxscale cannot get gtid_binlog_pos

error : [mariadbmon] Can not select 'master' as a demotion target for failover because it does not have a 'gtid_binlog_pos' and unsafe failover is disabled.

That error is logged whenever the replication isn't set up in a way that would allow safe failover to occur. This usually tells that there's something wrong with either the user the monitor is configured to use or that the replication was started in a way that isn't compatible with the automatic server management in MaxScale.

You can disable this safety check and force the monitor to create a simple topology by adding enforce_simple_topology=true to the monitor definition.

MaxScale MaxGUI tarball install MaxGUI error

Asked 2021-Jan-07 at 05:10

If you configure maxgui when installing with maxscale 2.5 tarball, the web browser does not display normally. However, if I install it at RPM, my web browser will display normally, but why doesn't it display normally when I install it with tarball?

This sounds like a bug in the tarball version of MaxScale. Please open a bug report about this on the MariaDB Jira under the MaxScale project.

Based on the output of the tarball installation, I suspect that the GUI files that the REST API serves aren't in the right place: by default they should be located in /usr/share/maxscale/gui/. If you copy the files there, I suspect the GUI will start working.

SQL 2005 is supported, but this was a bug which was introduced in version 4.3.0. There is currently a diagnostic patch for this issue for supported customers. The fix should be in the next patch level once we isolate the issue. If you'd like support just email help@appdynamics.com and they can assist. Thanks.

I have a similar setup (except for CLion), and I'm able to debug my STM32 board via STM32F4DISCOVERY (which has ST-LINK v2 on it). Perhaps if you follow my instructions, it will work out for you, too.

First of all, provide next flags to GCC when building your firmware:
