    Description

      Please write the documentation necessary for Statahead and AGL to be understood and used in Lustre 2.2. Please include any tunables that affect Statahead behavior. Only the raw content needs to be written - any grammar checking, spell checking, formatting, etc. will be done by a doc writer. The content can be appended to this ticket.

          It seems that statahead_status is no longer existed, but statahead_stats instead. Please confirm

          Yes.

          # cat /proc/fs/lustre/llite/lustre-ffff88007b31bc00/statahead_stats
statahead total: 318
statahead wrong: 0
agl total: 318

          The manual is still being updated...

          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

          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.

          Draft for statahead and AGL, it should be part of Lustre manual.
