[LU-673] poor coverage of directory operations in lustre client stats

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.3.0
• Labels: llite stats
• Assignee: WC Triage
• Reporter: John Hammond

Description

Directory operations are poorly covered by the Lustre client stats files (/proc/fs/lustre/

{llite,mdc}

/*/stats). In llite case, directory operations are simply not instrumented. For the mdc, the request opcode may not provide enough information to give a clear picture of what operations are being performed---the two main opcodes used for metadata requests (MDS_REINT and LDLM_ENQUEUE) are explicitly ignored.
