Hello,

I have read a similar post with detailed step about that, the main difference is that each of my VM disks is a single LUN (not a large LUN that stores raw or qcow2 disk images). I can:

- Resize the disk on the SAN host
- Rescan iSCSI session and upgrade multipath size on the proxmox servers

I was able to resize the disk inside the vm after i shut it down then started it again.

However, the old size is still showing up in the instance hardware list, and the new size is not notified to the instance kernel (it needed a cold reboot). Is there a way to tell Proxmox to rescan the disk and update its size (in the GUI) and notify the VM.

I'm not sure if `qm resize` safely applies to this kind of disk.

Thank you
Jerome
