Subject Could not fetch storage pool error
Date Thu, 15 Sep 2016 10:09:22 GMT
Hi all,
manually migrating some VMs from one host to another in anticipation of 
a maintenance, we were stopped by an error that does not allow us to 
migrate any other VMs.
We moved two VMs without problems and, after migrating the Secondary 
Storage VM it's now no longer possible to migrate further VMs due to the 
following error:
