Xenserver 6.5 Thin Provisioning Issue
-
And the benefits of mixing the two on the same storage device, which do exist, are much lower than having the whole thing be thin.

It's not provided anymore. Once you select it at install time, you don't need to select it again.
-
@Lakshmana It only uses space that is really used. It does not use the whole space you assign it. It's another way of over committing resources which that's the major uses of Virtualization.

You don't have to worry about it now. No need to doubt the software, it is by default thin provisioned now that you've enabled it during installation.

Exactly, you have already chosen thin provisioning. You do not see the option again because you have already chosen it. So all is well.

How to confirm the thin provision option is enabled after the installationOne of the ways you can do it (although it may be restricted on XenServer) is to create a virtual hard disk bigger then the space available. If it allows you to then you have thin provisioning enabled... if it fails then you don't. Of course this could cause a string of other, more serious issues.

What does this command show?
xe vbd-list

Shoot, I thought that that would say explicitly that they were thin provisioned.
-
This is not something the XS has well documented. They mostly expect you to just remember.

What about this xe sr-list

In my client the person does not know about thin provisioning.Then how he will find now.I also working towards it now?

This is an IT thing and not something that a client should know anything about. If the client doesn't know how to check, why does he care? Something is wrong that you are in this situation. It's like "how does the customer know that the engine as 24 valves". If the customer doesn't know how to check, then they don't need to care. If they know how to check, they don't need to ask you. You can answer that it was installed with thin provisioning and that is how Citrix tells you. Citrix does not provide a way to know, so he is asking for something you cannot provide. This is his problem.
-
If he insists, tell him to check with Citrix how to do this. He is not paying for support and Citrix does not document how to verify this.
