Take a look at this thread: http://www.gossamer-threads.com/lists/linux/kernel/1332888 I'm not an XFS guru, but it seems that XFS does a bunch of checks just on/after mount, so perhaps PgSQL cannot access /var/lib/pgsql/data immediately. You could igive it a try forcing some delay in systemd conf file, or tweaking the PgSQL startup script. -- Alberto Cabello Sánchez Universidad de Extremadura -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
