hello,

in the start of the year , an expert was mandated for our client to make his centreon clean .

Right from the start , he make the high avaibility cluster on the qualification side .

.

He made it with mysql 1.3 instead of 1.5 ( for some reason the repository for mariadb 1.5 , install the 1.3 version).

He should have stop here , the prerequisite of mysql 1.5 was not meet. but he did it anyway.

He was let go before ending his work and didnt revert what he did.

Today i cant upgrade , it ask me to upgrade mysql but i cant ( always the same not resolved issue with the repo ) .

We try to use a save from all of the servers but the change where already in place , and we cant go on last year because we switch from centos to redhat on january.

I cant revert the dnf install of the update.

I tried to reverse the HA , but it dont work.

How can i reverse the HA , to not be in cluster anymore like it was before , and reuse the DB that was in place before ( and with the good mysql version ) ?

Thanks in advance for your time and maybe response .
