iSCSI help with Proxmox 6.2-15

[jeremyricci]

Hi All,

I was able to successfully get an iscsi target hooked into my environment. As a test I created a vm - but it obviously used the entire 2tb disk. I then read that I should create an LVM on top of the iscsi and went through the setup wizard only to find the cfg.lock problem that seems to plague everyone. At that point, someone suggested to destroy the volume on my LenovoEMC px6-300d (which I did). I created a new iscsi volume and mapped it back to the hosts and unchecked "use Luns directly" per another suggestion.

When I attempt to create an LVM on the iscsi volume, I am now faced with the error pictured in the screenshot attached "prox-iscsi02.jpg". The first picture "prox-iscsi01.jpg" is just a screenshot of the settings used for the creation.

There does not appear to be a lot of info on this, although I did some articles referencing Proxmox 5 none of these seemed very helpful.

Does anyone have any shoves in the right direction I can chase down? It seems I'm half-pregnant and it's possibly something fairly obvious that I am just not seeing.

Any help would be greatly appreciated.

Thanks!

how many network adapter you have for iscsi??

 

[jeremyricci]

Each host has 8 I believe but I am only using 1 or 2 of each, do you think adding additional adapters might be the issue?

probably useful to post the output of

cat etc/pve/storage.cfg

and

pvesm status

to aid diagnosis

if you use more of one network adapter for iscsi you need to configure multipath.......

remember that if you use proxmox 6 or more for multipath configuration you need to adjust multipath.conf

Here is a screenshot of both commands. I also did just install multipath-tools on both nodes since that seems to be a consensus requirement

I have only 1 nic enabled on each node and the iscsi nas has 2 nics which are load balancing for the record it's a Lenovo EMC PX6-300d
