Consider options for persisting metadata about ceph-csi HOT 11 CLOSED

What are the current metadata stored that are supposed to be persistent and are not node-specific, for rbd and cephfs, respectively? from the linked PR the rbd snapshot info seems to be one of them.

from ceph-csi.

Yes, snapshot info and both rbd and cephfs CSI plugins store volume attributes.

I'm playing around with having etcd as a metadata store. Is it ok to have it as a dependency @rootfs ?

from ceph-csi.

Note that RBD allows you to associate arbitrary key/value pairs to images via "rbd image-meta get/set".

@gman0 i would like a cli option to persist meta data in kubernetes api server (e.g. as a configmap). This option can disable meta data persist if the driver runs in mesos.

@dillaman thanks for help. this case is a bit tricky since we want to persist both rbd as well as ceph cluster meta data.

Is this just for snapshotting, or are other uses also affected?

from ceph-csi.

Also other uses.

Also if snapshotter container is not start in the same node as provisionner container, trying to create a snapshot result in: Source Volume ID csi-xxx-xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx cannot found cannot found
