Subject Re: Force cleaning primary storage.
Date Mon, 02 Feb 2015 20:13:48 GMT
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
