fio 的全称是 flexible I/O tester,是常用的磁盘性能测试工具。fio 通过产生一系列的线程或进程来执行用户指定的特定类型 IO 操作。典型的用法是用户将需要模拟的 IO 负载写入到 job file 中。fio 支持多种 IO 引擎,通过 ioengine=io_uring,我们可以在 fio 中使用 io_uri
通过上述步骤,你应该能够解决“fio: blocksize too large for data set”的问题。如果问题仍然存在,可能需要更深入地检查你的fio命令和数据集配置。
The 'filename' option is used to specify host, port of the hdfs name-node to connect. This engine interprets offsets a little differently. In HDFS, files once created cannot be modified. So random writes are not possible. To imitate this, libhdfs engine expects bunch of small files to...

You could have someone dirtying large amounts of memory in a memory mapped file, or maybe several threads issuing reads using asynchronous I/O. fio needed to be flexible enough to simulate both of these cases, and many more. Fio spawns a number of threads or processes doing a particular ...

fio is a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user. The typical use of fio is to write a job file matching the I/O load one wants to simulate. OPTIONS--debug=type Enable verbose tracing of various fio ...
