Hi Liam, All, We have also run into this bug: https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/PCYY2MKRPCPI... Like you, we are also running Octopus 15.2.3 Downgrading the RGWs at this point is not ideal, but if a fix isn't found soon we might have to. Has a bug report been filed for this yet? - Dave
