@All,

Dan has now shared more info on his setup, anyone out there know of any known issues with
KVM not cleaning up primary storage.

@Dan - can you confirm we are talking about Root volumes and not Data Volumes

Regards

Geoff Higginbottom

Hi, Geoff,
  Thanks a  lot, here are the details:
1. CloudStack version: 4.4.1
2. Hypervisor:  KVM
3. Primary storage is NFS, but system.vm.use.local.storage is set to true.
And:
expunge.delay
360

expunge.interval
3600

expunge.workers
1



Cheers,
Dan
