Hi Everyone,
We are trying to workaround failed backups due to https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/2003866 . We used to use --single-transaction, but the option now requires RELOAD or FLUSH_TABLES. We failed to enable the privileges for the mwuser.
MediaWiki's backup documentation is at https://www.mediawiki.org/wiki/Manual:Backing_up_a_wiki . Here is the command MediaWiki recommends:
mysqldump -h hostname -u userid -p \ --default-character-set=whatever dbname > backup.sql
But the article does not discuss how to ensure consistency for the database and dump file. For MySQL, that should be --single-transaction or --lock-tables. (If I am reading the MySQL documentation correctly).
My question is, what should we use to ensure consistency of the dump file?
--single-transaction or --lock-tables or something else?
