Hello, I'm trying to deploy a simple wordpress installation following the documentation from kubernets. https://kubernetes.io/docs/tutorials/stateful-application/mysql-wordpress-persistent-volume/ kubernets was deployed using magnum on openstack rocky using the following template: https://paste.xinu.at/sRk/ Then i'm using the cinder storage class that is described in kubernets documentation: https://kubernetes.io/docs/concepts/storage/storage-classes/#openstack-cinder and I also made it default. I did the following test: cinder volume created before hand and used in pod directly with the id, the volume is attached and mounted correctly like is described here: https://docs.openstack.org/magnum/latest/user/#storage Now if I try to deploy wordpress using the first link or other helms that use volume claim, the volume is created automatically by kubernets but they are never attached or mounted to the instances. On master I see the following error: pv_protection_controller.go:116] PV pvc-48fed935-5b61-11e9-9901-fa163e5ebeae failed with : Operation cannot be fulfilled on persistentvolumes "pvc-48fed935-5b61-11e9-9901-fa163e5ebea> the object has been modified; please apply your changes to the latest version and try again Is there something I miss? I'm using the wrong version of fedora-atomic? It's the latest version available for download. I did find that someone else had this error but not with cinder: https://github.com/kubernetes/kubernetes/issues/72905 -------------- next part -------------- An HTML attachment was scrubbed...
