#文件队列的最大字节数 (the default value of 100mb,obs must be set to 250MB, which may cause the OSD start to fail frequently)

#文件操作的最大并发线程数 (the default value of 1,obs should be set to 2)

#文件写磁盘的时间间隔 (the default value of 5,obs should be set to 3, and increasing the frequency of write disks can reduce the number of IO per write and reduce the chance of block)

#xfs文件系统写磁盘的开始时间设置 (the default is 500, the small file store object-oriented storage should be set to 15, and when the number of IO accumulates to a certain number to start writing, the higher the number, the higher the chance of a block, but a low number will reduce the IOPS of the cluster)
