So after quite a few attempts to build a slave and getting the error above, I decided to start with no binlogs from scratch so on the latest slave rebuild I issued PURGE ALL BINLOGS BEFORE NOW() on the master to get rid of all the possible binlogs without GTIDs, then made a full dump with innobackupex and moved it to the slave. Started the slave up and it worked fine... Up to the point where I always get this exact error which is when I restart the master.... so after a mysql restart on the master is executed the slave lost connection of course, after reconnecting I got greeted with the usual:
"Got fatal error 1236 from master when reading data from binary log: 'Found old binary log without GTIDs while looking for the oldest binary log that contains any GTID that is not in the given gtid set'"
This is getting ridiculous now, I have rebuilt the slave 4 times now in 3 days.
Here's my my.cnf:
[client] port = 3306 socket = /var/run/mysqld/mysqld.sock [mysqld_safe] pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock nice = 0 open_files_limit = 65535 [mysqld] user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /srv/mysql tmpdir = /tmp lc-messages-dir = /usr/share/mysql explicit_defaults_for_timestamp bind-address = xxxxxxxxx key_buffer = 64M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 16 myisam-recover = BACKUP table_open_cache = 512 open_files_limit = 65535 interactive_timeout=180 wait_timeout=180 query_cache_limit = 1M query_cache_size = 256M slow_query_log = 1 slow_query_log_file = /var/log/mysql/mysql-slow.log long_query_time = 10 max_binlog_size = 100M expire_logs_days = 10 log-error = /var/log/mysql/error.log sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES symbolic-links=0 innodb_file_per_table innodb_additional_mem_pool_size = 20M innodb_buffer_pool_size = 24G innodb_file_format = "Barracuda" binlog-format=MIXED log-slave-updates=true log-bin gtid-mode=on server-id=1 enforce-gtid-consistency=true [mysqldump] quick quote-names max_allowed_packet = 32M [mysql] [isamchk] key_buffer = 16M
At the time of master restart, the slave was about 4000 seconds behind already (that's what I was trying to solve somehow, but I got this error - again -)
I case you are wondering last time I rebuilt the whole thing was last night, so it is not a case of missing binlogs due to expiry.
Does anyone have any idea?
