No local storage
Ok so it didn't create any storage for you at all to use, meaning you have to manually create an SR. Follow the guide I posted just above.
-
Ok, let me follow the guide.
I'll report back in a few -
Your mileage may vary with that guide, since you have many drives presented to XS.

Also wouldn't it be the smarter choice to go with EXT4 over EXT3?
EXT4 has some oddities that made some people (XenServer) not trust it completely. I'd say XFS would've been a better choice at the time, and brtfs should be the future.

XFS is what I had been expecting. Going to ext3 again is just silly.

I'll steal the most-moderated title if I say what I think about sticking with ext3.

Not a chance...

Does Xen support btrfs? I wonder if the upcoming release of XS with Xen 4.7 will give us more supported options.

I ran this cmd's, rebooted the host & now I'm able to create SRs
dd if=/dev/zero of=/dev/sdb bs=1M count=1024
dd if=/dev/zero of=/dev/sdc bs=1M count=1024

@FATeknollogee
when you looked at the volume layout after XS was installed, did it create an ext3 volume and just fail to mount it?One thing I'm not sure if someone has successfully tried yet is if they can manually mount an ext3 volume that's larger than 2 TB into XS or if there is some sort of limit in XS that prevents it.
-
Isn't 2TB the max size of ext3?

I thought we found it's 16 TB

Xen does I believe, the limitation has always been XenServer, not Xen.

How about the message: "One SR will created that spans the selected disks"?
Just using the XS GUI install (no CLI), tried another install option...
1x 80GB for o/s + 4x 400GB for VM storage with Thin prov. enabled.
This option works as advertised.

Ah, I was thinking of file size.
I think the max file size is 2TB maybe?
Which might also explain things since the VHD can't be larger than 2GB.

The file system LVM doesn't support thin provisioning, simply.
It does. lvcreate -L +5G -T does a 5 GB thin provisioned.

Yeah that article I posted made it seem like it was possible...
And that was kind of my line of questioning of this...that other systems (such as Hyper-V) support thin provisioning. It is a technology, not EXT.
