Swift read problems

Hi all, I'm trying to benchmark my swift install using COSBench and I'm seeing lots of read failures. The errors in the log are of the following format: object-auditor: ERROR Object /srv/node/v7ka1/objects/3342/0bf/e9e11ac7f28ea51d14ba0f4adb7b70bf failed audit and was quarantined: Hash of name in metadata does not match directory name and object-auditor: Quarantined object /srv/node/v7ka1/objects/3342/424/5d9bcded71875416d3c8d581e1a82424/1426251597.97548.data: Hash of name in metadata does not match directory name

Does anyone have any thoughts on why this might be happening and/or what to do about it?

The writes and deletes are both completing with 100% success so I'm at a bit of a loss.

Thanks in advance

Odds are that your /etc/swift/swift.conf is not the same across all your nodes, in particular the entries swift_hash_path_prefix and swift_hash_path_suffix. If those don't match, then the object auditor will compute a different hash than the proxy will for a given object name, and so it will believe the object corrupted.

Always keep /etc/swift/swift.conf the same across all the nodes in your cluster.

Thanks a lot, one of my nodes died and I must've forgotten to copy this across after my reinstall.

If an error is found, the corrupted object is moved to a quarantine area, and replication is responsible for replacing the data with a known good copy. Are you still seeing this error, as it's most likely not an issue any longer.
