Comment 17 for bug 1700585

Can you turn your proxies request_node_count [3] >= 84 (3 nodes * 28 devices) and check again for the 404'd objects.

Do you have any dispersion populate/report data you can query [1]?

Can you describe your device failure/replacement procedure [2]?

Can you check the quarantined datadirs on the hosts - it shows they're empty - could be a mis-config throwing off reporting - unless... how have you been handling corrupted data?

Since this issue is troublshooting a particular deployment to attempt locate data or discover underlying bug(s) - it might be useful to move this to #openstack-swift on freenode for more responsive feedback - and then take the results of the investigation to create issue(s) for whatever gaps are uncovered.

e.g. this may turn out to be be a duplicate of lp bug #1619408
