Description of problem:

When there is no space left on the device, and we are trying to write to the logs, few issues raise up (described in actual results)

Version-Release number of selected component (if applicable):
ovirt-engine-3.0.0_0001-1.3.fc16.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install ovirt using engine-setup utility.
2. Ensure you used 100% in your file system
3. Attempt to login Admin Portal

Actual results:

1. When trying to connect to the Admin Portal, it seems we are getting an error: "User is already logged in" (while on ovirt.log we can see that there is no space left on the device)
2. ovirt.log through SQLException 
3. Storage tab stays empty...

Expected results:

The Error printed on Backend side: "No Space Left On the Device" should be printed in UI also (login page & Storage Tab)
