Can you test using 'gluster volume set <vol> open-behind disable' ?

If works, I recommend enabling that option for all volumes in CNS (if this is critical behavior). Else, will close with a known-issue.

Comment 6 Atin Mukherjee 2018-11-19 08:15:18 UTC

Is this behaviour seen in latest OCS releases?

Comment 7 Amar Tumballi 2018-11-20 05:00:11 UTC

Considering there was no update on bug other than the initial filing, and not reported by the QE during any of OCS/CNS testing, closing it as WORKSFORME. Please re-open if seen again.
