mangix debug --0： scsi连接超时断开

测试大概17分钟的样子，osd、mds和client均未出错，可是测试程序停止执行，在mds和client上执行dmesg如下：

fs93:~ # dmesg
[ 4052.000006]  connection2:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4295902790, last ping 4295904042, now 4295905296
[ 4052.000014]  connection2:0: detected conn error (1011)
[ 4172.256063]  session2: session recovery timed out after 120 secs

 

bug：

  osd内部打印日志过于频繁导致响应client和mds的request太慢，超过了scsi驱动的时间限制，导致超时，连接自然断开，程序停止。

fixing-method：

  关闭大部分log，提升osd模块处理速度。

test_result：
