Further development of iSCSI functionalities in Proxmox VE

[Felix Driessler - inett GmbH]

Hi all,

we're looking to extend the functionality of iSCSI in Proxmox, based on Timo Veith's request back in April. [0]

Before we start implementing we'd like to know if there are any related ongoing/past developments and if such changes fit the project.

These are changes we plan to contribute:

    1. Improvements to the GUI:
        a) Better Disk Image names, when configuring a VM with iSCSI (Multipath) Storage:
            Currently, Disk Images have Names such as "CH 00 ID 0 LUN 0", which are hard to correlate to Disks on the iSCSI System. Instead, additional Information such as WWID should be visible.
        b) Addition of Multipath path healthiness to the GUI (as can be seen with multipath -ll)

    2. Changes to iSCSI Configuration:
        a) Addition of optional CHAP Authentication
        b) Configuration of multiple Discovery Portals for iSCSI storage’s, in case iSCSI systems do not announce all Portals

    3. Resize/Re-scan & other Life-cycle features
        a) Addition of a refresh button or something similar to fetch LUN Information again
        b) Online resize of LUNs (visible on Hypervisor as well as in VM); Either automatically or with a manual refresh button
        c) deletion and cleanup of unused LUNs

    4. LVM Support for Multipath Devices
        a) Creation of LVM-PVs on Multipath Devices using the GUI/CLI

We'd appreciate feedback if any/all of these changes or of interest and if we can move forward with implementing them.

Regards,

Felix Drießler
