Re: [Bacula-users] mysqldump not working due to missing password

You're right I messed up missing to pass the --defaults-extra-file in the mysql command and thus it would fail trying to get the list of databases. Messed around in a VM an got to the same conslusion. I changed the config now I'll see tomorrow how it went. Thanks for the tips.

Still is there a way to have the Job fail on an error like that?

Is the "ERROR 1045" coming from `mysql ...` or from mysqldump?

I suspect confusion about users and defaults from your description.

1. The ClientRunBeforeJob runs in the bacula-fd. Are you really running
that as the bacula user? Normally it runs as root.

2. You are passing '-u root' to mysql so this is not connecting as the
bacula user and might be different from your tests with 'sudo -u bacula
mysql'.

3. You are not passing --defaults-extra-file to mysql (only to mysqldump).

4. You are not passing '-u root' to mysqldump, so the user will either be
specified in /var/spool/bacula/.my.cnf or defaulted to the user running the
command (probably root in the ClientRunBeforeJob).
