mariadb-dump creates empty backup without error message/code

    XMLWordPrintable

Details

    Description

      Example (binary logs enabled):

      1. mariadb-dump --user=root --all-databases --flush-logs --master-data=1 --events --triggers --routines > /tmp/full_dump.sql
      2. echo $?
        0
      3. ls -lah /tmp/full_dump.sql
        rw-rr- 1 root root 1.3K May 30 14:56 /tmp/full_dump.sql

      Backup is nearly empty...

      Reason:

      SQL> FLUSH LOGS;
      ERROR 1004 (HY000): Can't create file '/var/log/mysqld_error.log' (errno: 13 "Permission denied")

      This is really ugly. I would expect a return code Unable to render embedded object: File (= 0 AND an error message) not found.
