Okay … #OwnCloud #OCIS #InfiniteScale doesn't work with #Ceph #RadosGW, because Ceph is incompatible with a sent header https://tracker.ceph.com/issues/64465, and disabling PutObjectDisableContentSha256 https://github.com/owncloud/ocis/blob/v5.0.5/services/storage-users/pkg/config/config.go#L154 doesn't have _any_ effect.
Anyone got OCIS running against Ceph S3?
