    When you have a single master and multi node fog architecture, does the master replicate to each of the storage nodes one at a time or does it replicate to all at the same time?

    Fog 1.5.9 running currently on all servers

      @The-Dealman The replicator is pretty simple in that it should be a sequential replication node by node. If I remember correctly the images are replicated based on their image ID sequence and not by image name. You can prove this out by looking at the fog replicator log. There will be a master replicator log and then one log per storage node.

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

        @The-Dealman As George said, take a look at the logs to see the current status of replication going. It replicates image by image but kind of parallel to all storage nodes.The actual replication of one image to one storage node is started as a background job and so it is mostly going all in parallel.

        Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)
