Hello, after upgrade from ceph 19.2.5 to 20.2.2 (and now I'm on 20.2.3), I have big problem to write any bigger blocks of data to S3 buckets. My config: CEPH on HDD, everythink works fine. We are using not only S3 RGW, but RADOS for images of virtual machines - without problem. I have 9 host with total 108 HDD. On 4 fast machines I have RGW containers. CEPH cluster is maintained by cephadm (podman). I have haproxy, which do gateway to RGW and maintain Let's Encrypt certificates. After upgrade to 20.2.2, everythink PUT requests gets 502 HTTP code. I've manage Veeam backup of M365 and some rustic backups. Today I've tried this: 1) I've created new bucket 2) I set this bucket for rustic (rustic init) with user, which is Owner of this buckets. 'rustic init' was fine. 3) I've tried to do backup: 'rustic backup'. No one block of backup data was written. Please, can you help me? Many thanks. Sincerely Jan Marek -- Ing.
