I totally agree with @KeithK_LC in the analysis, I wouldn't risk to get a ClearPass crash due to a disk filled with crap from another server on the same storage system.
My lab servers are provisioned with Thin provisioned disk and works pretty good. But in earlier versions I have run into problems with thin provisioned computers when trying to perform a major version upgrade. When the secondary partition where about to be initiated the process stopped. Don't remember the version I had this issue. Haven't tested in 6.11 or 6.12.

Not a designer, but I would suspect it is to guarantee there is no over provisioning of your disk within VM. Given the criticality of ClearPass (ie Network Access can stop altogether for everything depending on your implementation) it is imperative to prevent anything that can be prevented from stopping the system dead.

Hi
were in the midst of upgrading our clearpass server, it seems the requirement for the disk is Thick Provisioning, is this still compulsary? If anyone knows the logic behind why the disk type needs to be Thick instead of thin, would appreciate and feedback.
I can understand it if the underlying storage has limited space but what if the underlying storage has more than enough free space? cant we set the disk type to thin provisioning in that case?
TIA
