Large file copy failing at around 78% every time.

[jons]

Trying to copy a SQL DB from one VM running Windows Server 2003 to one running Windows Server 2008, both latest versions. File is around 50GB in size. Previously used xcopy /j for such tasks, but looking for a better solution and found ViceVersa. Running the latest version for evaluation purposes and every time we attempt, it fails around 78%.

This is an unbuffered file copy from VM to VM. Both thick provisioned. ViceVersa gives the error:

windows copy error. not enough server storage is available to process this command

There's plenty of disk/storage space available. I've found other similar issues online, but I can't narrow down what the issues could be. Any insight would be greatly appreciated.

Figured it out after hours of testing. Looks like the host server that the SQL DB file was being copied from (Windows Server 2003) needed to have IRPStackSize entry added to the registry. I followed the advice of a site I found and ViceVersa copied the files like a champ. Adding this to help anyone that runs across this in the future.

HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Services
\LanmanServer
\Parameters
IRPStackSize DWORD

default size is hexadecimal 15. I upped mine to 30.
