 Please note, it's much better to have nodes with roughly same space(500Gb and 5Gb in same grid is not a good idea,if you for some odd reason must have them both - read http://bigpig.org/twiki/bin/view/Main/VolunteerGrid2Philosophies and think again,if you still think you must - don't count them in S in below calculations)
-Let's say S=number_of_nodes), setup k=3,N=S,h=N-2,
-use N=number_of_nodes_total, h=N-2

 '''[=#Q25_sharespreading Q25:] Is there a process or command to make shares spread to new storage servers?'''
 
-A:
-No. Not yet. ;) Such a process will probably be implemented and there is a ticket ([https://tahoe-lafs.org/trac/tahoe-lafs/ticket/232 #232], [https://tahoe-lafs.org/trac/tahoe-lafs/ticket/1657 #1657], [https://tahoe-lafs.org/trac/tahoe-lafs/ticket/699 #699], [https://tahoe-lafs.org/trac/tahoe-lafs/ticket/661 #661], [https://tahoe-lafs.org/trac/tahoe-lafs/ticket/543 #543]) for it.
+A: This is called "rebalancing". It isn't currently implemented, but the repair function can accomplish a similar result sometimes. Repair of immutables will upload shares to servers if necessary to reach "servers-of-happiness", which sometimes has the desired effect of uploading shares to newly added servers. Repair of mutables never uploads new shares. Here are tickets about improving rebalancing behavior: #232, #1657, #699, #661, #543.
