I've never had a lock tables issue. But the problem is that the search table is trying to be updated whilst you are Dumping.

Generally speaking you should consider putting the store into maintenance mode during a dump to prevent data loss or other issues as MySQLDump does attempt to lock the tables so it can see how much data it needs to load from the whole table. (It doesn't want to miss newly added data so it locks the table but something else has locked it.

You can use the --lock-tables=false option on the MySQLDump command line. But I'd go with Maintenance mode myself.

--lock-tables, -l

Lock all tables before dumping them. The tables are locked with READ LOCAL to allow concurrent inserts in the case of MyISAM tables. For transactional tables such as InnoDB and BDB, --single-transaction is a much better option, because it does not need to lock the tables at all.

  • what would be the best command for it? will it be "mysqldump -u root -p --lock-tables, -I --single-transaction magento > magentobackup.sql" ? I'm a newbie to all of these – user3705550 Mar 30 '16 at 0:59
  • It's best to experiment and see what works for you. For me a straight flat mysqldump with no special arguments works fine. BUT thats for MY use case. – Barry Carlyon Mar 30 '16 at 8:58
