 Specifying a property with an empty value, which is often done for `EncodingProfile.IsMaster`, will match if this property does not exist at all on a ticket. So for `EncodingProfile.IsMaster`, specifying an empty filter will match on recording tickets which never have this property. Specifying a property with an empty value, which is often done for `EncodingProfile.IsMaster`, will match if this property does not exist at all on a ticket.

-The first variant is typically used for events with more than one room. For bigger events we use the dedicated [[hardware:event-storage|storage]] server in the event server rack, for smaller events a USB connected hard drive to one of the minions might be sufficient. Each recording cube exposes the files via rsyncd, which are pulled by an rsync process running inside a screen on the storage pc.+This variant is typically used for events with more than one room. 
  
-For each encoderX start rsync on the central storage: `sudo systemctl start rsync-from-encoder@encoderX.lan.c3voc.de`+For bigger events we use the dedicated [[hardware:event-storage|storage]] server in the event server rack, for smaller events one of the minions is typically sufficient. If you use a minion as storage machine, you might want to configure `10.73.0.2` (aka `storage.lan.c3voc.de`) as secondary IP address to make things easier:
  
-Then, start tracker workers on storage: `sudo systemctl start crs-worker.target` (only needed if you don't use `storage.lan.c3voc.de` - worker scripts get started automatically)+  sudo ip a add dev br0 10.73.200.24/16
  
-==== Minion setup 
  
-To allow the encoding workers to do their job, they need to mount the storage first: `sudo crs-mount <storage location>`+Each recording encoder exposes the files via rsyncd, which are pulled by an rsync process running on this storage machine.
  
-After mounting, you can start the tracker encoding workers: `sudo systemctl start crs-encoding.service` 
  
-The minion VMs running inside our event colo case automatically mount `storage.lan.c3voc.de` via cifs and start their worker scripts. You usually do not need to touch them.+For each encoderX start rsync on the storage machine:

-Similar to variant 2, but extended to work with multiple rooms. Instead of using rsync, recorded snippets remain on the encoding cubes and ''/video/fuse/$event/$room'' are exposed via samba to the minions, while the encoded and tmp files live on one "central" minion; all other minions mount ''/video/encoded'' and ''/video/tmp'' from the primary minion [reasoning: the tracker cannot guarantee that the machine which encoded a talk also does the postprocessing (upload) step, so all minions have to see the same files].+Similar to variant B, but extended to work with multiple rooms.

 Tracker filters have to be set only for the recording cubes, minions do not require any filters (but on smaller events without many minions, a ''EncodingProfile.IsMaster=yes'' filter can be a good idea, so sub formats won't crowd out the queues — they can always be encoded off-site later). Tracker filters have to be set only for the recording cubes, minions do not require any filters (but on smaller events without many minions, a ''EncodingProfile.IsMaster=yes'' filter can be a good idea, so sub formats won't crowd out the queues — they can always be encoded off-site later).
