I think ACS preserve all VHDs for coalesce but coalesce not occur when create a template or before starting next snapshot scheduled. If I create a template from any snapshots (2) showing in GUI, the template have 49GB. 49 GB is the size of the 2 latest files on secondary storage.
What do you think? Bug? -----Original Message----- From: Rafael Weingärtner [mailto:rafaelweingart...@gmail.com] Sent: quarta-feira, 25 de outubro de 2017 22:07 To: users@cloudstack.apache.org Subject: Re: Strange size of template from snapshot on XenServer Aha, The two destroyed entries are showing " removed: NULL". In ACS one thing is the "destroying" of a resource, another is the removal of this resource from the system. I believe there is something to do with the expunge interval, but I am not sure if the snapshots complete removal also happens within the expunge interval of user VMs or if it is configured by something else.
