Description
This article explains how to enable Thin Provisioning on XenServer.
Instructions
By default, a new SR in XenServer will be formatted in LVM, which does not support thin provisioning. So if you add an SR and you don’t explicitly specify ext3, your disk will default to thick provisioning.
1. You can enable thin provisioning at installation time:Select Enable thin provisioning (Optimized storage for XenDesktop) in the drive selection screen.
2. If you have already installed XenServer and you want to enable thin provisioning on a new drive that is adding, you need to use the CLI. The only prerequisite to enable it is that the drive must be formatted in ext3.
#xe sr-create host-uuid=$host_uuid content-type=user name-label="SR name" shared=false device-config:device=/dev/sdX type=ext
