[LU-8503] Replay-single test-66b: @@@@@@ FAIL: Worst 6 should be worse than orig 6

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.11.0
• Severity: 3
• Assignee: WC Triage
• Reporter: Ashish Purkar (Inactive)

Description

The replay-single test_66b invokes lookup to initiate a RPC. Running this test successively causes the lookup to fetch inodes from cache without sending RPC. This results in test injection failing. Replacing lookup with touch resolves this issue.
