Base Disk is not being deleted by MCS on 7 1811.1

Mark Veldman




I see in the forums that there was a bug in an older version of Apps/Desktop 7 that Base Disks are not being deleted. (7.15)


I think that we still have this issue, because when i look on our storage, i see many copies of the Base Disk (see screenshot).


Can someone help me out how to check and safely remove the unused disks?

Our storage is full, and some weeks ago we already extended the storage by 500GB.

But i think because of the bug it's full everytime.

Hey Jim,

Thanks for the link, that's exactly what i was searching for.

I tried this on our Test Environment, and cleaned up the old duplicates.

Thanks again!

I would like to ask if https://support.citrix.com/article/CTX222886 is just a workarround or a final solution for this issue?


My environment ist currently on 7.15 LTSR CU3 and I was facing the same behaviour until I find this CTX Article. 


I also find out that in CU5 kind of MCS issue has been fixed:

   ->> Attempts to delete a base disk image using Machine Creation Services (MCS) might fail. [LD2143]


Not sure if this is reated to the actual issue.
