%% Newer versions of Riak may use different on-disk formats of riak.
|
|
%% When performing a rolling downgrade, the downgraded nodes may not
|
|
%% be able to read the newer on-disk format. This tests that riak_kv_format
|
|
%% correctly downgrades the on-disk format on a node while performing a
|
|
%% rolling downgrade.
