Hi, I've found out some more details. The message > > initdb: directory "/var/lib/postgresql/data" exists but is not empty > > If you want to create a new database system, either remove or empty > > the directory "/var/lib/postgresql/data" or run initdb > > with an argument other than "/var/lib/postgresql/data".
is not an error for the entire service. It's initdb refusing to clobber the existing database (which has been created by the postgresql-service instance with no #:config-file argument) and helpful in preventing data loss. The actual problem only arises because guix reconfigure doesn't deem a change in service arguments as reason to restart (or reconfigure) a service. I.e. before, my config was: (postgresql-service ) Then I did guix reconfigure ... Afterwards, I changed the config to: (postgresql-service #:config-file ...) Then I did giux reconfigure # this erroneously doesn't reload the postgres service!! > > and the error message still references the default config file. > > I don’t see any references to a config file in what you pasted. In the postgres-service definition in guix/gnu/services/databases.scm , there's a %default-postgres-config . That's what I meant. At all times, the default config file was printed in the log - which was because the postgres service never actually was reconfigured. >I’ve tested ‘postgresql-service’ in a pristine system with ‘guix system vm’ >and it starts without any such message. So I guess there’s stale data in >/var/lib/postgresql/data on your system? It was left over from the first unsuccessful launch because bug# 22618 hadn't been fixed at the time. Thanks, Danny
