IntelliCache Question - Cannot creat MachineCatalog


Uwe Meyer

Question

Hi,

we have an working XenApp Farm. Now i would like to use the intelliCache function. I delete the local Storage and recreate them with an ext3 Filesystem and enable the host Caching.

I follow this Articel: https://docs.citrix.com/en-us/citrix-hypervisor/storage/intellicache.html

 

Now i create a new Ressource in Citrix Studio with IntelliCache enabled and shared Storage.

 

Then the MachineCatalog was created with the following error:


 

Inner Error:
Storage does not support local storage caching

ErrorID : PluginUtilities.Exceptions.OperationNotAvailableException

Can someone help?

 

Is there a good tutorial for this?

 

Thanks for help.

Regards

Uwe

Have you followed these instructions as well? (The formatting on the docs page is a bit wonky, I'll see if we can get that fixed)

xe host-disable host=hostname
localsr=`xe sr-list type=ext host=hostname params=uuid --minimal`
xe host-enable-local-storage-caching host=hostname sr-uuid=$localsr
xe host-enable host=hostname

In particular the host-enable-local-storage-caching is crucial

Also, if that was an existing machine catalog then I think you might need to either recreate it or make some configuration changes to the Hosting Connection (I can't remember how much you're allowed to change on an active connection and how much has to be set on creating a new one).
