write behind operation warning. What's it mean.
Hi Martin, This typically means that the client attempted to write to a disk that is getting close to full, or has quotas enabled. There is a situation where files written to a disk that is almost full/or quota almost exceeded can end up corrupting files; see q-article (in microsoft support database) q290861. http://support.microsoft.com/support/kb/articles/Q290/8/61.ASP Basically the message itself hearkens back to ms clients being able to transfer data in a 'write-behind' mode, which means that,essentially, they trust the server to actually write the data to disk AFTER the smb has been responded to. So if for some reason the actual disk write cannot be performed (file system full, exceeded quota), the client doesn't actually find out about it till the next smb request... Microsoft reported a problem with this in its MCIS software as well in q article q193932, though it's probably not related to your problem. Whether it's actually a PROBLEM or not depends on how the client/application that was doing the write handles it; it could attempt to re-write the data, or return an error up to the user of the application indicating that the operation (a save, whatever) failed. Check with your users on this pc to see what they are doing, and if they have experienced any application errors... Hope this helps, Don -----Original Message----- From: Martin Rootes [mailto:M.J.Rootes@shu.ac.uk] Sent: Wednesday, April 11, 2001 5:52 AM To: samba@samba.org Subject: write behind operation warning.
