How to extend LVM over iscsi?

Question

LVM

Good afternoon, the essence of the problem I have is this.
There are 4 Proxmox nodes and a common IBM Storwize v3700 store connected via iscsi
There is a Lun on the store that I needed to expand, it went without problems using the command:
"expandvdisksize -size 2 -unit tb vmvol01"
On the nodes, the lun looks like a physically connected disk (sdc. sdf. sde, etc.) and with the lsblk command, I also see that the disk has increased. I run the pvresize command, the command works successfully, and pvs displays the old volume to me =(
What's wrong? I can't reconnect the lun, since there are lvm disk images for virtual machines.
