StarWind x Proxmox SAN Integration storage not found

[lff_seth]

We just set up a new 4 node Proxmox cluster with external SAN. Like many others, I ran into Proxmox's limitation when it comes to iSCSI and LVM-thin so I decided to install this plugin. Everything with setup was going great but when I started my first VM I began getting "TASK ERROR: storage 'swlun' does not exist" errors even though it was in the list when I created the VM. When I click on the node and go to LVM-thin I can see that a "lvmth-100" thinpool was created successfully. Below are screenshots of the VM hardware, LVM-thin pool, and Datacenter storage. What am I doing incorrectly? I'm not very experienced in this area so apologies if I'm missing something obvious.

Welcome to StarWind Forum! Was that VM running on the lun before you installed the plugin?

Thanks! No, this is a newly created VM after setting up the plugin. I did figure out a little more since making the post. If I remove the VM from HA then it boots up perfectly fine, it only fails when HA is trying to start the VM. Also, I didn't mention it in my original post, but we are on Proxmox 9.1.1.

Hi,

Thanks for your update. Could you please check if the LUN has the same ID in multipathing on all nodes?

Sorry for the delay in replying, took off for the weekend and didn't see an email notification.

Below is the output from "multipath -ll" on all 4 nodes. Does this answer your question?

Thanks, I will log the internal testing request.
For now, the solution is likely to be running without the plugin or without the HA.

Well shoot... that's not the answer I was hoping for, haha. I appreciate the help.

[yaroslav (staff)]

Yeah, sadly I will need to wait for my team to do their bit.

After rebooting all 4 nodes, the problem disappeared! My VM seems to be running without issue now

Magic. Great news!!
Thanks for your update.

One more question, the plugin is working great as of now but I'm hesitant to put it into production without proper support channels. Does Starwind offer any support plans for the plugin?

[yaroslav (staff)]

Hi,

Nope. That's free software. We can support it bundled with the VSAN offering from us, though.
I can be wrong here. For more info, you can log a support ticket with us https://www.starwindsoftware.com/support-form so we will put you in contact with your account manager.
