Comment (by lenzenmi):

 I'm using the revised file, and it seems to work well.

 One thing I have noticed is that the tahoe_server_disk_used graph shows
 the total space used on the filesystem where tahoe is running, not just
 the space used by tahoe shares.

 I took a quick look at the stats.pickle file, and the only disk usage
 values I see are:

 free_for_root
 disk_total
 disk_free_for_non_root
 disk_avail
 disk_used

 None of which give you the stat for the space consumed by the grid.  I
 know the share total is available from each server, and can be gathered by
 the node specific tahoe_storagespace munin plugin, but this needs to be
 installed on each machine that runs a server.

 I suppose this should probably go into a new ticket, but perhaps we could
 add the tahoe_storagespace stat to the stats.pickle file that's collected
 by the stats-server?

 As a workaround, new installs of tahoe could be made to their own
 filesystem, so the disk_used and tahoe_storagespace numbers are
 equivalent.
