How do I mount this as a SR in XenServer 6.5

@Dashrender said
I don't know enough about Linux and partitions, can EXT3 support 14 TB?
I really wanted to ask this at MangoCon 2016 after the @travisdh1 presentation on LVM. How XS "messes" it up so much, or makes it so different from regular Linux.

XS 6.5 has 2TB limit on local storage volumes:
Where did you read that in that document?
-
This is completely irrational that the local array has a storage cap of 2TB !
There is no way.... 2TB.... so I have to create a billion LVM arrays ?

No, I read that wrong. Sorry.

It doesn't. But we arent talking about LVM here.

Mostly because it does things for you, like logical volume creation and the file system. Them sticking with ext3 for so long has really started to hurt the platform, I think that's where the 2TB limits come in.

Right but every discussion involving LVM and EXT and XS always seems to include the phrase "because it's XS"...

See? You could have talked more about this.
Stupid fire alarm.

But scott found that he was mistaken on the 2 TB limit.

Ok so install is going to USB, without selecting the array as "local" storage.
Even though the installer offers it as a choice.

Ok so here is what I'm going to try.
Install XS to the USB, and not select the presented array for the local storage.
From this, I'll try to add the array to xs as a local repo, using GPT.
Okay, so the same kind of procedure you would do if this was ESXi, for example.
Actually, for the last 30 mins, other than skipping picking an SR during install, this is what he's been doing. The assumption would be that XS would automount the 14 TB drive as an SR, but for whatever reason it's not.
We know from Dustin's posts that XS is creating a sba3 for the remaining space that XS itself doesn't use. That space is created as EXT3. I don't know enough about Linux and partitions, can EXT3 support 14 TB?
Nope. Gotta create multiple 2TB volume groups and add each of those perhaps?

It is. Files on EXT3 are limited to 2TB. The full filesystem is limited to 32TB.

So if it's limited to 32TB, how do I add this array, it's half that size.. . .?

And here comes another XS/LVM/EXT discussion.

I'm making no sense, nope, I've got a 6TB ext3 volume on my desk right now....
Did we ever see the output of?

@travisdh1 not relevant at the moment (performing a clean install)

https://support.citrix.com/article/CTX121896
does this article assume the local disk to already have a partition on it?

My local SRs on 6.5 are over 2TB
lvm not ext though. -

Was already here when i started
My guess is after though. I would be able to say for sure if there was any documentation for our XS infrastructure when i started. There wasnt.
