1.首先明确猫盘群晖系统中经常控制风扇相关IO失败导致写日志,已按教程把日志输出内存中,即tmpfs.2 I) o; G Q& c
- #scemd bind
- touch /tmp/scemd.log.new || true
- chmod 660 /tmp/scemd.log.new || true
- chown system:log /tmp/scemd.log.new || true
- mount -o bind /tmp/scemd.log.new /var/log/scemd.log || true
- #2 }. }3 t9 L0 ]$ s+ b7 D7 @6 Q9 ~& e' C
$ N+ S, i, y/ o8 j7 J
+ N s% Z4 v& x7 T5 phibernationFull.log日志文件中可以看到相关信息已写入tmpfs3 B8 p1 T* X% [

但是连着发现有写磁盘操作如下:

3 g2 |/ C: C8 j5 P7 D, b

接着使用ps -ef命令打印所有进程,找到esynoscheduler相关的进程信息

到这里看不懂了,请问3条bash写操作是怎么产生的,应该怎么关闭?
