We now run all the daemon with a new option from Nautilus 14.2.1 which allows us to tell to a daemon to not log on file. However, we can decide to activate logging by editing the configuration flag 'log_to_file' via the centralized config store like this for a particular daemon: ceph config set mon.a log_to_file true This is useful when a daemon keeps crashing and we want to collect log files on the system. Fixes: https://github.com/rook/rook/issues/2881 Signed-off-by: Sébastien Han <seb@redhat.com>
