-------------------------------+---------------------------
 {{{
 < Sagi> suppose I currently have 3 nodes online. When I set N=6,K=H=3,
 every
         node gets two shares. Now if one fails, I still have my data
 < Sagi> in addition, one of the shares on the remaining two can get
 corrupted.
 < zooko> Sagi: right.
 < Sagi> configuration.rst says "A value of shares.happy <= k is allowed,
 but
         does not provide any redundancy if some servers fail or lose
 shares."
 < Sagi> that is incorrect for this situation, then.
 < Sagi> I think that sentence is only correct when gridsize >= N
 < zooko> Sagi, I believe you are exactly correct.
