After setting up the replication in Maria DB, I was seeing error message in the error log and show slave status\G out put and the replication is working.
ERROR:
[ERROR] Slave I/O: Unable to load replication GTID slave state from mysql.gtid_slave_pos: Table 'mysql.gtid_slave_pos' doesn't exist, Internal MariaDB error code: 1146
So I tried a `mysql_upgrad` which told me to try --force as it looked already up to date, so I tried --force, which gave:
mysql.gtid_slave_pos
Error : Table 'mysql.gtid_slave_pos' doesn't exist in engine
status : Operation failed
I checked in the db/mysql folder and found that the .frm and .ibd is aready existing.
gtid_slave_pos.frm
gtid_slave_pos.ibd
I just removed the files and recreated the table with MyISAM engine, which solved the issue.
STEPS:
Go to the mysql folder ( default path in column store /usr/local/mariadb/columnstore/mysql/db/mysql )
drop the following files:
rm gtid_slave_pos.frm
rm gtid_slave_pos.ibd
mysql -uroot -p -s mysql
MariaDB [mysql]> show slave status \G
