so many block volume left in the worker node

[leoliudan]

Hi guys

I found there are so many volumes(blk) left in the worker node as below
I guess those block volumes are not detach from the worker node when the pods are moving to other worker nodes.
is this a known issue?

[Qeas]

Could you please share the driver version used?

[leoliudan]

k8s:1.22.4
NexentaStor CSI driver block:1.4.2
nexenta:5.3

[leoliudan]

for the config node.session.scan in /etc/iscsi/iscsid.conf
do we need to set it to auto or manual?
