a simple solution, in config_opts.h, add a configuration item osd_op_force_delete, default is false or true? in the class OpReques，add two function need_skip_full_check(), set_skip_full_check() in the OSD::init_op_flags, add checking, if there is a delete op and osd_op_force_delete is ture, call set_skip_full_check. in the OSD::handle_op, when checking full, we can skip it by need_skip_full_check(). Is that OK?

So what?s your advice? Wish your reply, thanks. The workaround is to temporarily raise the full threshold so you can do some deletes. But you're right that a rados delete operation should be accepted in this state.
