适用场景

  • ONTAP 9
  • WaflIron

问题解答

警告: 手动将WAFL扫描速度值提高到较高值可能会发生原因对数据生产造成显著的性能影响。  只能在 NetApp 技术 支持的指导下更改

WAFL扫描速度:

  • 由nokeshell命令控制 wafl scan speed
  • 默认情况下、由ONTAP根据可用系统资源自动调整。
  • 影响为文件系统扫描分配的CPU时间。
  • 值越高、将 对 性能产生负面影响。
  • 不会影响阶段1安装时间。

 

更改 WAFL 扫描速度

  1. 根据需要检查当前速度:

::> set advanced
::*> run local wafl scan speed    
WAFL scan speed is 1300

  1. 将速度设置为2000并监控:

::> set advanced
::*> run local wafl scan speed 2000  
  
::*> run local wafl scan speed
WAFL scan speed is 2000

  1. 如果需要进一步增加、请按5%的增量进行。   
  2. WaflIron完成后、将扫描速度重置为自动调谐:

::> set advanced
::*> run local wafl scan speed 0   
 
::*> run local wafl scan speed
WAFL scan speed is 1300
