Question about iSCSI storage ("advanced options")

Hello,

First of all thanks a lot for this great piece of software !

I did not knew about Proxmox 2 weeks ago when I was about to set up a lab@home based on 2 NUC in order to play arround with ESXi. Main goal was to "consolidate" several virtualboxes/dockers (running on 2 Syno) and few raspberry pies.

I've followed a link while googling and ended up on PM website.

Now I have a running 2 nodes cluster with shared storage providing me (more or less?) all that ESXi/VCenter could provide me but for free (was about to use my VMware corporate's licenses btw).

I have two questions about storage. My LAB is based on 2 Synology providing NFS & iSCSI targets and 2 PVE nodes running pvetest (4.1.34).

1.- Could it be possible to assign a full iSCSI target to a VM instead of just having the option to add LUN by LUN ? As I provision my LUNs by target, storage side, it may help as well when adding a LUN on the NAS to have it automatically available to the VM(s) linked to this specific target.

2.- I've configured two VMs with Veritas InfoScale 7 (formerly Storage Foundation) and each VM has access to the same iSCSI LUNs on both NAS. I use Volume Manager to mirror the data on both NAS. I know it's a bit overkill but that's my job and I'm skilled to easily manage/debug this type of configuration Vs drbd/pacemaker. If I attach 2 LUNs coming from NAS1 and 2 LUNs from NAS2 to the VMs (using virtio controller) all LUNs are "tagged" by Volume Manager as if they're from the same enclosure and named virtio0_0 (1st LUN of 1st virtio enclosure) to virtio0_3 (4th LUN of first virtio enclosure).
Could it be possible to split LUN to several virtio controllers in PM in order to "see" virtio0_0/virtio0_1 for LUNs from NAS1 and virtio1_0/virtio1_1 for LUNs from NAS2 ? This will help to know what is coming from what and to configure mirroring based on enclosure ...

Thanks in advance !
