          Fix landed for 2.8. We'll reopen if this issue still is hit on Hyperion. If there is still an issue at SDSC and it is not, as hoped, a duplicate of this issue then please open a new ticket to track that issue.

          Rick, this particular issue existed in IO READ code path and doesn't related to LU-7106. I check OSD code quickly and didn't notice other similar issues at first glance.

          Yes, we're scheduling a PM and push this out. Could this patch be related to LU-7106? In other words could the current code create an error that propagates back to the client as ENOSPC even when there's capacity on the OST?
