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. -- Erik On Tue, Nov 11, 2014 at 7:03 AM, yogendra singh <yogendra8si...@gmail.com> wrote: > correct. it shows it reaching 100%, but when I am going inside the VM, I am > seeing so much of free space. even anything starting inside the VM.
