@ -255,7 +255,38 @@ directly from FLU `b` again ... we should see something different.
That is correct! The command at prompt #20 automatically performed
"read repair" on FLU `b`.
### 6. Exploring the rest of the client APIs
### 6. Exploring what happens when a server is stopped, data written, and server restarted
Cut-and-paste the following into your CLI. We assume that your CLI
still remembers the value of the `D` dictionary from the previous
steps above. We will stop FLU `a`, write one thousand small
chunks, then restart FLU `a`, then see what happens.
{ok, C3} = machi_cr_client:start_link([P || {_,P} <- orddict:to_list(D)]).
machi_flu_psup:stop_flu_package(a).
[machi_cr_client:append_chunk(C3, <<"foo">>, <<"Lots of stuff">>) || _ <- lists:seq(1,1000)].
machi_flu_psup:start_flu_package(a, 4444, "./data.a", []).
About 10 seconds after we restarting `a` with the
`machi_flu_psup:start_flu_package()` function, this appears on the
console:
=INFO REPORT==== 21-May-2015::15:53:46 ===

=INFO REPORT==== 21-May-2015::15:53:47 ===
Repair success: tail b of [b] finished ap_mode repair ID {b,{1432,191226,707262}}: ok

The data repair process, executed by `b`'s chain manager, found 1000
chunks that were out of sync and copied them to `a` successfully.
### 7. Exploring the rest of the client APIs
Please see the EDoc documentation for the client APIs. Feel free to
explore!
