Description of problem:

if master domain consists of luns that are smaller then 10G and we have vm's on the domain we will fail reconstruct after host reboot with StorageDomainDoesNotExist error

Version-Release number of selected component (if applicable):

vdsm-4.9.2-0.65.gitf945dc2.fc16.x86_64
ovirt-engine-backend-3.0.0_0001-7.fc16.x86_64

How reproducible:

100%

Steps to Reproduce:
1. create 2 domains on 2 different storage servers: 1 with 50G, second consists of several lun sizes (anywhere from 2-25G). 
2. attach both domains to DC - the second domain should be master
3. create a few vm's (with disks)
4. reboot host
  
Actual results:

when the host goes up it fails reconstruct with vdsm error

Expected results:

we should not fail reconstruct

Additional info:full logs attached

please note that this is not a high priority bug because we only fail reconstruct when we have small luns and if we have vm's on the domain.
