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

  Warning  ExternalExpanding  13s (x2 over 126m)  volume_expand  Ignoring the PVC: didn't find a plugin capable of expanding the volume; waiting for an external controller to process this PVC.
looks like some config missing in our setup, can you help spot that.
FYI - longhorn version 
v1.3.0
can we get some help around this issue

Can you provide use the support bundle?
a
@icy-agency-38675 not quite understood - support bundle?
b
@acceptable-printer-7134 You could download the support bundle via Longhorn UI.
a
ok my question what is that bundle for? also a quick question 
does dynamic volume resizing
supported for longhorn volumes? like we edit the PVC to upsize the volume.
b
1. The support bundle contains system information and logs You can check this https://www.suse.com/support/kb/doc/?id=000020145 2. Regarding 
does dynamic volume resizing
, maybe this document what you want.https://longhorn.io/docs/1.3.2/volumes-and-nodes/expansion/#expand-a-longhorn-volume
