we tried editing PVC to expand storage. didn't help...any logs we can see @creamy-pencil-82913 i am thinking to check longhorn manager logs on the node where pvc volume is attached.
i see this message for pvc events

looks like some config missing in our setup, can you help spot that.
FYI - longhorn version 
v1.3.0
https://github.com/longhorn/longhorn/issues/3724
can we get some help around this issue 
Expander.NodeExpand found CSI plugin <http://kubernetes.io/csi/driver.longhorn.io|kubernetes.io/csi/driver.longhorn.io> to not support node expansion
any config missing in longhorn?
not sure if anyone around to help 😞

does dynamic volume resizing
supported for longhorn volumes? like we edit the PVC to upsize the volume.
