Mariadb 10.3 has changed the position in the replica without human intervention










0















I have the following problem:
Yesterday, due to an unknown error the replication stopped working on the 3 slaves of my master server. I have mariadb 10.2 on the master server on two slaves 10.3 and on another 10.2. The error is described as shown in the log below. In log 'miservidor-principal-bin.005515' at position 261112394 the replication was stopped for hours until at a moment without any intervention in the servers with mariadb 10.3 a change was made and registered in the log: reconnecting to retry, log 'miservidor-principal-bin.005516' at position 11324538, the server with 10.2 remained dropped while those with 10.3 managed to recover by setting a new position arbitrarily. Is there any explanation for this? I have no idea what happened here. Will data have been lost when making that change? It is normal ?

The error is described as shown in the log below. In log 'miservidor-principal-bin.005515' at position 261112394 the replication was stopped for hours until at a moment without any intervention in the servers with mariadb 10.3 a change was made and registered in the log: reconnecting to retry, log 'miservidor-principal-bin.005516' at position 11324538, the server with 10.2 remained dropped while those with 10.3 managed to recover by setting a new position arbitrarily. Is there any explanation for this? I have no idea what happened here. Will data have been lost when making that change? It is normal ?

      I have the following problem:
      Yesterday, due to an unknown error the replication stopped working on the 3 slaves of my master server. I have mariadb 10.2 on the master server on two slaves 10.3 and on another 10.2. The error is described as shown in the log below. In log 'miservidor-principal-bin.005515' at position 261112394 the replication was stopped for hours until at a moment without any intervention in the servers with mariadb 10.3 a change was made and registered in the log: reconnecting to retry, log 'miservidor-principal-bin.005516' at position 11324538, the server with 10.2 remained dropped while those with 10.3 managed to recover by setting a new position arbitrarily. Is there any explanation for this? I have no idea what happened here. Will data have been lost when making that change? It is normal ?

      mysql mariadb replication slave







      share|improve this question
















      I have the following problem:
      Yesterday, due to an unknown error the replication stopped working on the 3 slaves of my master server. I have mariadb 10.2 on the master server on two slaves 10.3 and on another 10.2. The error is described as shown in the log below. In log 'miservidor-principal-bin.005515' at position 261112394 the replication was stopped for hours until at a moment without any intervention in the servers with mariadb 10.3 a change was made and registered in the log: reconnecting to retry, log 'miservidor-principal-bin.005516' at position 11324538, the server with 10.2 remained dropped while those with 10.3 managed to recover by setting a new position arbitrarily. Is there any explanation for this? I have no idea what happened here. Will data have been lost when making that change? It is normal ?
