VSAN Free question regarding my configuration

Hi,

For your information : I could not wait and installed a trial version of VSAN, with the exact same setup. I only deleted the existing CVM on both hypervisors, imported new ones, and activated them with a trial key.
There was no problem creating the LUNs using the web interface.
I ran the checktargets script, in order to confirm the image paths created, as this was a setting we weren't sure about in the createHA_2 script we have to use with the free version.
(in our case : VSA Storage\mnt\nvme0n1p1\volume1\LUN1\LUN1.img)

I deleted the trial CVMs, and installed back the free CVMs, modified and double checked the createHA_2 script, but again : invalid partner info...

So there is definitively something wrong with the script used in the free version.

I understand the support is limited with the free version, and we could be happy being offered a free version, but why can't we have a sample script with all correct settings ? Ideally, we should only have to modify a few settings only for both nodes, like IP addresses and image path .

I hope we'll be able to test the free version, before considering upgrading to a paid version...

I am glad to know that it works. Please note that moving to FREE will not be possible.
As of the script, I think there was something wrong with the path, that's why I wanted to take a look at the system.
I noticed that $aluaOptimized is set to different values.
You can refer to this script viewtopic.php?f=5&t=5624&p=31505&hilit=tip+3#p31505. Please look carefully each parameter and align them carefully for each side.

Hi Yaroslav,
Thank you for your answer.
Well... it works with the trial version, but I would like it to work with the free version !

Indeed, we had so many tries that the script is now a mess. I carefully reviewed it :

Error code is desperately the same :

I'll try not to look at it until Monday, when we'll discuss about this.

Thanks,

It looks like there is something with backup header and the main one.
Let us revert to it on Mon!

Did this ever get resolved? I'm on the Free as well, trying to figure out LUNs via powershell. I was really confused until I found threads here mentioning it had to be powershell. I had figured there would be an example if it had to be via powershell. That coupled with no reference besides a listing of the scripts is a little baffling.

[yaroslav (staff)]

Yes, It was resolved.
The script for standalone device creation is called CreateImageFile.ps1.
Scripts are here viewtopic.php?f=5&t=6852&p=37208&hilit=HINT8#p37208

it is not possible to search for terms in the forum, so we have to browse every discussion

Fun fact that I found. It’s available on mobile, but you can also force the search icon to show up if you shrink a desktop browser window way down horizontally. Guessing it’s a theme issue?

[yaroslav (staff)]

yep. That's why I am using desktop appearance all the time.
