plotting to many destinations

[shegis-nn]

As I noticed -d flag adds copying finished plot to destination. This process is in the background (correct me if I'm wrong) so process did not wait and start plotting next plot. It is good for network location and save some extra minutes.

Is it possible to add more destination to feel more than one disk and some kind of space left checking?

We have multiple harvesters with many drives per machine. They fill up at slightly different speeds but all use the same docker container to plot. In the future, we will have a problem of moving plots around for efficiency. We don’t want to, for example, launch a container to plot to drive 15 if that drive is already full in some of the machines. We don’t want to use raid zero for final directories either because each machine has so many drives. Is Chia or MadMax planning to support multiple final directories or is there a good tool? Something that checks and creates a new plot to whichever final directory still has space. Any help is appreciated. Too many machines and directories to do it manually. Using Ubuntu server, MadMax and docker.

I think the best way is to start plotting in one process - it starts filling temp drive, and simultaneously second process (script) for something like that:

1. Check if there is new .plot file ready
2. if no: wait 30 sec
3. if yes:
   A) check first destination for free space
   o) if no, try next destination
   o) if yes, copy plot

looks easy for someone familiar with bash - so not for me ;)

You can use Plotman along side the chia-plotter.
Plotman has an archiving feature (local drives or rsync to network) that will search for a drive with available space and send your plot to it. You can also stagger the plots across the drives to reduce network clogging - plotter 1 sends to drive 0 first, plotter 2 to drive 1, plotter 3 to drive 2, etc..

Just set autostart_plotting = false in the plotman.yaml so it only archives the plots

#60 goes over why this probably won't happen.
Have you considered combining all your disks into a JBOD array so it appears as one drive?

aufs with round-robin and low space control is perfect for this

aufs sounds like what I need, but I can not seem to find much written on it.
