Summary0001419: Mariadb plugin - problem with incremental backup

I have problem with incremental backup on mariadb plugin.

Fatal error: python-fd-mod: Could not get LSN with command "echo 'SHOW ENGINE INNODB STATUS' | mysql -r | grep 'Log sequence number' | awk '{ print $4 }'", Error: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

Everything is fine with a full backup.

I think there may be a problem with incremetal backup not adding authorization options to the mysql command.
Steps To ReproduceRun incremental backup.

Maybe you're missing the mycnf plugin configuration ?

If you have a look at the documentation (which still need to be published)
the access to mysql (most of the time by root) need to be automated by using .my.cnf technics and so and should works.

So in your case as user root
echo 'SHOW ENGINE INNODB STATUS' | mysql -r command call should work without any errors.

Any news ?

At the time of writing, there was nothing in the documentation about the mariadb plugin, so I did it without .my.cnf. Now everything is ok.

Yeah the merge of the documentation took much time than expected.
It is now available, and we your confirmation I will close this issue.
