[LU-17371] OFD ALR records should not be generated for maintenance operations

• Type: Improvement
• Resolution: Unresolved
• Priority: Minor

• Severity: 3
• Epic Link: Hot Pools backlog

• Reporter: Andreas Dilger

Description

The OFD access log reader generates records for files that were just created and are being written for the first time.

This can be confusing in the case of background filesystem maintenance operations, such as "lfs mirror *", "lfs migrate", and "lfs hsm *" operations that incorrectly give the impression that the file is under active application usage when it is not.

There should be a mechanism under which these background maintenance operations do not inflate the heat of files.
