A full disk followed by repair leads to SIGBUS on Open():

  • One Riak instance with eleveldb enabled. Data directory is in devrel node
    on the same disk as Riak and it's logs.

* basho_bench configured with:

%% Prepopulate database to ~1Gb using 1k objects - requires 750k

%% Make sure this is max/infinity so the populate completes
{mode, max}.
{duration, infinity}.
%% Make this a multiple of final key size - partitioned_sequential_int keygen is fussy
{concurrent, 10}.

%% Set up bucket to use - configure with n_val=1
%% using riak_core_bucket:set_bucket(<<"b1">>,[{n_val,1}]).
%% from riak console
{riakc_pb_bucket, <<"b1">>}.
{key_generator, {int_to_bin, {partitioned_sequential_int, 0, 75000000}}}.
{value_generator, {fixed_bin, 1000}}.
{operations, [{put, 1}]}.

%% Riak connection info
{riakc_pb_ips, [ "" ]}.
{riakc_pb_replies, default}.

%% Setup cruft
{driver, basho_bench_driver_riakc_pb}.
{code_paths, ["deps/riakc",


  • This is allowed to exhaust disk space during the benchmark. The benchmark halts,
    as riak stops. No message is logged (presumably because disk space is exhausted).
  • leveldb::RepairDB() called on leveldb/0
  • leveldb::DB::Open() called with option create_if_missing=true on leveldb/0
  • See: "Bus error" from SIGBUS and program abort with stack trace:
