XenServer 7 install to Dell R730 OBR10 15TB

Ok so here's what I've figured out.
You can manually create the LVM partition (I did so by following this) and it it comes out as lvm2.
See the details below.
-
And there is the completed storage in XS7.
-
Just to recap (for my own sanity)
LVM is the default, but. only if the storage is less than 2TB?
If more that 2TB, XS "automagically" does Ext3?
You can "switch" back to LVM via CLIIs this correct?
-
I created this storage as LVM, and it set it to LVM2.
I didn't try to create the storage as EXT3.
-
Thanks for the update

In your case, what's the advantage of LVM2 vs LVM?
-
From this installation, even when I chose to select the storage from the installation, it didn't create any local storage.
So I had to manually create the storage repository for the system.

Ask the XenServer developers, I just set the type to "lvm".

You mean that screen shot in your 1st post did not work?

Not in the way it should've. Selecting the 14.9 TB array during installation, did not create the Local Storage.
But I was able to do so following this.

Have you checked if Thin Provisioning is on? I don't think that it works with lvm SR
-
@momurda I looked this up one time before, and found an answer.
-
@momurda Yep, you're right it is Thick provisioned.
for anyone wondering the command to check your SR.
xe sr-list uuid=<SR UUID> params=all

There is no LVM on Linux. LVM2 is all that there has been for a very long time. LVM is the name of the family and category, like this...
Does Linux have an LVM? Yes
What is the name of Linux' LVM layer? LVM
What is the version of LVM on Linux? LVM2 -

It can't be. Thin provisioning in XS is ext3 and thick is LVM. It's not that they are doing thin on ext3, it's that the terms are used interchangeably. Thin is a code name for ext3, thick is a code name for LVM. The act of mounting LVM makes it thick.
-
@scottalanmiller So should I destroy this SR and try to create it as EXT3? and if I do can I migrate a thick provision vm over to a thin provisioned host?

Migration should be fine, but I've not done it. Should you be ext3? That's up to you

There's obviously not much choice if one desires Thin prov.?

My question is converting the storage to thin going to break my VM's if I import them from a Thick provisioned system...
If you don't have the answer, just say so.

Also wouldn't it be the smarter choice to go with EXT4 over EXT3?
