 Hi y'all!


Small ansible question: I have this ansible playbook which uploads and
runs a script to set some permissions in the database. This worked fine
while the playbook was only executed on a single server, but now that
mailman01 and 02 are being setup for prod, the script is executed on both
machines, and tries to set the permissions in the same DB server at the
same time, which produces a psycopg2.InternalError (tuple concurrently
updated).

Any idea how I can ask Ansible to not run this task in parallel on both
servers? Any other way around this?


Thanks,

Aurélien
