So, testing: 1. I tested running an AWS instance (Ubuntu 14.04) into 100% IOWAIT, and the shutdown didn't kick in even when storage went full "d" state. It's possible that other kinds of remote storage failures would cause a shutdown, but don't we want them to?
2. I tested deleting /pgdata/* several times (with pgbench running), and Postgres shut down within 20 seconds each time. 3. I tested messing with the permissions on pg_control and global, and Postgres threw other errors but continued running. 4. I mv'd the files and that didn't trigger a shutdown. 5. I did a fast swap: rm -rf /pgdata/* cp -p -r /pgdata2/* /pgdata/ ... as expected, this did NOT cause postgres to shut down. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
