-问题：把 metadata 操作随意派发到任意线程，容易卡住或回调不回来。
+blobstore metadata 操作与创建线程/通道绑定。
 
-根因：
+需要明确 metadata thread 和 io thread 分工。
 
-- blobstore metadata 操作与创建线程/通道绑定。
-- `resize/delete/unload` 内部会走 `spdk_for_each_channel()` barrier。
+### resize 导致程序卡死
+- `resize/delete/unload` 内部会走 `spdk_for_each_channel()` barrier。大概是让其他的spdk线程同步resize之后的状态才能返回。所以如果要做要尽可能少做resize。
 
-修复策略：
-
-- 明确 metadata thread 和 io thread 分工。
+如果其他spdk线程持有iochannel，并且没有持续poll，就会导致卡死。
 - 保证持有 channel 的线程持续 poll。
 - 线程退出时严格释放 channel，避免 barrier 永久等待。
 
-### 6.2 Daemon 卡住（请求已收但流程停滞）
-
-现象：请求日志打印到一半后卡住，压测进程阻塞。
-
-根因：
-
-- UDS 流式读取没有完整分帧处理。
-- 固定小缓冲导致回包序列化失败（`serialize resp failed`）。
-
-修复：
-
-- 改为连接级接收缓冲，循环读到 `EAGAIN`。
-- 按“完整包”消费，残包保留到下一轮。
-- 回包序列化改为动态缓冲 + `send_all`。
