Samba 3.6 Released With SMB2 Support
Jeremy Allison - Sam wrote in to let us know the Samba project has made a major new release. The main highlight is support for SMB 2.0 which was released as part of Windows Vista. There are a number of other improvements to printing support, clustering, and identity mapping; details can be found in the release notes.
SMB2 communications occur when you have a Windows Vista (and above) communicating with Server 2008. If you're using XP or Server 2003 in any combination with the newer OS, it steps down to SMB1. The thing to realize is that SMB2 doesn't handle oplocks well. So legacy file-based databases will break and become corrupted when communicating over SMB2.
I can't find the KB, but per Microsoft, they highly recommend using SQL and not files for future databases as SMB2 will most likely break that functionality. I can vouch for this advice as I've seen some strange shit in this regard.
Life is not for the lazy.
We've handled that case since the mid 1990's...
Jeremy.
