Thanks for getting this content created FanYong but we should keep the ticket open until it has actually landed in the manual. We'll get this reassigned now. |

I found the section in manual that talks about statahead 31.2.7.2.�Tuning Directory Statahead ... /proc/fs/lustre/llite/*/statahead_status This is a read-only interface that indicates the current statahead status. It seems that statahead_status is no longer existed, but statahead_stats instead. Please confirm |
