PVC property in linstor volume/resource definition

[phoenix-bjoern]

For debugging we often have to check the status of the volume/resource in the linstor CLI. Therefore we first have to check the PV name the CSI driver has generated for the PVC. With the PV name we can then execute linstor v l|grep <pv_name> to see what the actual status of the volume/resource in DRBD is.

To ease that process it would be helpful to write the PVC name to a custom property of the volume and/or resource. In addition the linstor command should be extended to add a column for additional properties specified in an argument (but this feature request has to be raised at https://github.com/LINBIT/linstor-server). With that you could easily find out which ResourceName (PV name) and DeviceName belong to the PVC name, which significantly will speed up analysis.

Is that a feature of general interest?

Yes, it's something that's been requested a few times. What would need to happen:

• enable the --extra-create-metadata option on the csi-provisioner
• update linstor-csi to support the extra parameters passed in The main question is how this information is then passed to LINSTOR. I believe there is already a "ExternalName" field that could support arbitrary strings for names.
