The attempt to allocate more storage for the virtual disk %1 has failed.
                 

                 
Check the available capacity of the virutual disk; you may need to add additional
                 
physical capacity to the pool.
                 

                 
Once you have resolved the condition listed above,
                 
you can online the disk by using the following commands in PowerShell:
                 

                 
Get-VirtualDisk | ?{ $_.ObjectId -Match "%1" } | Get-Disk | Set-Disk -IsReadOnly $false
                 
Get-VirtualDisk | ?{ $_.ObjectId -Match "%1" } | Get-Disk | Set-Disk -IsOffline  $false
