Damn, that took me 20 mins to get through (my most recent post before this was made when I started reading the thread).
While the requirement to use spanning sucks, it's a decent solution to this problem that really shouldn't be any more problematic than having a single large partition once it's configured. Given the choice between using spanning or buying a third party NFS mounting software for Windows, then buying external storage that supports NFS, then mounting that storage to Windows via NFS to then be shared out to users through Windows via NFS (possibly creating an IPOD) - yeah I'll keep spanning.
I'll agree with this. Otherwise <---- Gun to head, or we be $$$$$ throwing big money for full on NAS/SAN solution for HA setup.

You're still limited to the 6 drives per VM though. So the max total you can have period is 12TB per VM.
Edit: Ah that was 6.2 Looks like 6.5 has a limit of 16 VDIs.
-
@johnhooks Which that is 32TB of storage on a single VM.

Is there a simple way to make a QCOW based file that XS will use?

Now that I don't really understand. You wouldn't need HA for the SAN/NAS situation if you aren't doing it with local storage.
For example, you have one XS server, and you direct attach a SAN/NAS storage solution to it. Have you made it more complex more points of failure, sure, but so much so that you need to make it HA? Probably not, at least not in this case. Why not? Because you're reason for going to SAN/NAS isn't HA, it's to solve a single storage presentation problem, which you would be solving through either iSCSI or NFS or SMB most likely.
But I still wouldn't do this over a spanning solution.
-
XS's VHD limitation is akin to the old LBA limitation.
And in this case you'd be using external storage to solve it by doing to a different connection method/protocol, bypassing XS altogether. -

Wait a min, what? isn't what you describe - a storage SPOF an inverted pyramid of doom?
That is indeed inverted pyramid, per Scottalanmiller descriptions and article.
When I mentioned IPOD earlier - I was thinking that their was an expectation that many servers would be accessing the storage... I see not that wasn't what this discussion was about - so I stand corrected.

Wonder why XS hasn't moved to VHDX?
Any thoughts?

Or QCOW, the native format???

I second this. QCOW would be better.

Still no reason for folks to run ProxMox in Business environment? I know I got hit over the head before making this mention
-
I wonder how the conversion would go for EXT3 to QCOW, along with the VM conversion.....
-
Right, doesn't have to be VHDX, just anything that supports larger than 2TB.

Only stuff I can find is converting from qcow2 to VHD or the other way around.
I found a good utility to convert from
.xvato.img, then just used qemu to convert the.imgto.qcow2. Sadly that doesn't help us here haha. -
Is there a limit to how many 2TB VDs you can span?
-
@BRRABill 16 in XS.

That answer confuses me.
Do you mean you can only have 16 VDs for a VM in XS?

I can't imagine any reason for it. It's got a few basic issues that will never go away...
- It's an endemically evil company that you don't want to associate with
- The core idea is bad - mashing two different virtualization solutions together on one box
- They just make the GUI, not the products, so they themselves likely know nothing special about it
- It's non-standard so getting assistance or support is hard
- It has no real benefits to offset the negatives.
-
You can have 16 vDisk per VM in XS.
Yes

EXT4 -> XFS
VHD -> QCOW
