So I was able to make another array, and was also able to make an SR on that array. It's still strange that I'm not able to use thin provisioning by default on install, but for now, it's working.

Easy enough to add to XS7 I assume, but sucks that it isn't the default.

My situation wasn't a snapshop - it was a fast copy.. so I'm not really sure.

@Dashrender said: Right, but when you're working with files that large - why bother storing them in a VM - just st.... OK yeah, that goes against the standard practice now.. so we need a VM, even if the whole host is a VM - welp, I guess your stuck with XFS Pretty much. EXT4 is pretty silly for a server of any size, which is why even for desktops RHEL is XFS by default and EXT4 only as an option for advanced users. EXT4's days are pretty much over.
