[ceph-users] Cloud sync to minio fails after creating the bucket

Hi list, I'm currently implementing a sync between ceph and a minio cluster to continously sync the buckets and objects to an offsite location. I followed the guide on https://croit.io/blog/setting-up-ceph-cloud-sync-module After the sync starts it successfully creates the first bucket, but som

[ceph-users] radosgw-octopus latest - NoSuchKey Error - some buckets lose their rados objects, but not the bucket index

Good day people, we have a very strange problem with some bucket. Customer informed us, that they had issues with objects. They are listed, but on a GET they receive "NoSuchKey" error. They did not delete anything from the bucket. We checked and `radosgw-admin bucket radoslist --bucket $BUCKET` w

Hello everybody, I had an HW failure and had to take an osd out however I now got stale+active+clean. I am okay with having zeros as replacement for the lost blocks, I want the filesystem of the virtual machine that is using the pool to recover if possible. I can not find what to do in the

[ceph-users] RBD Images with namespace and K8s

Hi all, we created a RBD image for usage in a K8s cluster. We use a own user and namespace for that RBD image. If we want to use this RBD image as a volume in k8s, it won’t work as k8s can’t find the image - without a namespace for the RBD it works. Do we have to set something special here ?
