Error 1012: There was a mapping failure on Windows Storage Server 2003

Paul Maglinger — Mon, 09 Mar 2009 20:41:35 GMT

Running Windows 2003 Storage Server R2 on a HP Proliant DL380 G4 with 3GB memory connected to a HP EVA3000. We are using it to serve out both Windows and UNIX (NFS) shares. In some cases, some of the directories are shared out
as both Windows and UNIX, sometimes the UNIX share is a subdirectory of the Windows share. Occasionally we will start seeing an event ID 1012 nfssvr - There was a mapping failure. When this happens, we occasionally get errors from the HP-UX server complaining about an I/O error. There are no errors on the EVA which would indicate a drive or controller problem. This typically occurs when we are copying a large amount of files. Those of you who Google this will no doubt see when I put this out about a year ago. Things seemed to work somewhat better after I made the registry change recommended, setting HKLM\System
\CurrentControlSet\Services\NfsSvr\Parameters\SecureHandleLevel to 0 in that I usually don't have to reboot the server anymore but I'm still get the 1012 errors and more importantly the I/O errors. Now that it's been a year, just wondering if there are some fresh thoughts out there?

There are a number of hotfixes available for SFU/SUA including one or two for NFS resource related problems.

Great link, but I have a question. The hotfixes reference Windows Services for Unix. This being a Windows Storage Server, it has Services for NFS. Is this the same thing? The "About" page for the Microsoft Services for NFS show it as version 1.0. Is there something newer or do I upgrade to Services for Unix?

No solution found *sigh*... Will continue to search...
