Subject Re: Fwd: Issue with Primary storage
Date Tue, 11 Nov 2014 08:44:46 GMT
If you're using thin provisioning or overprovisioning you may very well
allocate more than you're physically able to fit.

What your VM sees is based on the virtual disk image size and does not
refer to any underlying infrastructure.

Your problem is that the underlying storage is full, so when your VM tries
to physically allocate more space it cannot.
