Re: Max Message Size For AIO calls

Looks like this here is the relevant config option:

    osd_max_write_size which has a default value of 90 megabytes
(adjusted below with the << 20) in my tree

In osd/OSD.cc:

    // too big?
     if (g_conf->osd_max_write_size &&
         m->get_data_len() > g_conf->osd_max_write_size << 20) {
       // journal can't hold commit!
       service.reply_op_error(op, -OSD_WRITETOOBIG);
       return;
  }
