[Maria-discuss] Regarding Automatic fail-over - Maxscale
by Karthick Subramanian 16 Aug '16

16 Aug '16

Hi All, Can anyone help me to figure out this. I am planning to use Binlogrouter for replication (single master and single slave topology). I read from google forums for maxscale that with binlog router, it'snot possible to use automatic failover. Did anyone try this. >From google forum ( https://groups.google.com/forum/#!msg/maxscale/DnFT4eb0BbQ/cHQ3TLEfBAAJ;con… ) "With the 1.3.0 version of MaxScale, the binlogrouter accepts STOP SLAVE, START SLAVE and CHANGE MASTER TO ... commands. These can be used to change the master server but automating this process with the repmgr is not currently possible. Since the binlogrouter supports the normal slave management commands, using something like MHA could be possible: https://code.google.com/p/mysql-master-ha/ " Could anyone help me to understand whether I can use binlog router along with automatic failover feature using maxscale. I have read this blog using shell script we can achieve, but not sure whether with binlog router, it ll work?

by bbnlaccts acnts 16 Aug '16

Hi, I am trying to set up a master slave replication between 2 servers running mariadb 10 on centos 6.7 In the initial setup itself i keep getting HA_ERR_KEY_NOT_FOUND. I have tried all methodology based on my novice knowledge ro rectify but in vain. i am new to this env. Any help will be greatly appreciated. - Server version 10.0.23-MariaDB-log - Protocol version 10 - UNIX socket /var/lib/mysql/mysql.sock. The scenario I have followed is this: 1. Shut the prod (mc1), took a cold backup and restored on slave (mc2). 2. On master ran show master status; prodarchivedlogs-bin.000001 and the pos as 582240 3. Set these info in slave. 4. Started the slave, it started throwing up error: 160812 3:31:50 [ERROR] Slave SQL: Could not execute Update_rows_v1 event on table radius1.radacct; Can't find record in 'radacct', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log prodarchivedlogs-bin.000001, end_log_pos 587695, Gtid 0-1-79, Internal MariaDB error code: 1032 160812 3:17:18 [Warning] Slave: Can't find record in 'radacct' Error_code: 1032 160812 3:17:18 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'prodarchivedlogs-bin.000001' position 587072 I have tried all methods based on my knowledge, but it is just not functioning. I tried using mysqlbinlog tool to extract to a file and then tried inserting, even then it is failing. Any help will be greatly appreciated.

[Maria-discuss] New Question: ST_AsGeoJSON

Hello, A new question has been asked in "Geographic Functions" by dbauszus. Please answer it at http://mariadb.com/kb/en/st_asgeojson/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Are there plans to implement ST_AsGeoJSON in MariaDB? This is by far the most widely use format to present data in web mapping applications. It will be a large overhead if we need to format records in the client prior to rendering the data on a web map.

[Maria-discuss] Known limitation with TokuDB in Read Free Replication & parallel replication ?
by jocelyn fournier 10 Aug '16

10 Aug '16

Hi, After upgrading from TokuDB Enterprise with MariaDB 5.5 to MariaDB 10.1.14, I tried to enable the parallel replication (parallel_mode=optimistic, slave_parallel_threads=4) on a GTID enabled RFR slave, but it leads to random failures. (both master & slave are running 10.1.14) E.g : Could not execute Update_rows_v1 event on table sc_2.sc_param_index; Can't find record in 'sc_param_index', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.008418, end_log_pos 217608066 If I issue a start slave (with sql_slave_skip_counter=0) : Could not execute Update_rows_v1 event on table sc_2.sc_log_cron; Can't find record in 'sc_log_cron', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.008418, end_log_pos 218275984 If I put back slave_parallel_threads to 0, the slave keeps replicating happily without any issue. Is this a known limitation with TokuDB ? Tokudb configuration : tokudb_rpl_lookup_rows=0 tokudb_rpl_unique_checks=0 tokudb_pk_insert_mode=2 tokudb_directio = 1 Thanks and regards, Jocelyn Fournier
