Hi, had samba 2.1.?? version and Win2k running for some time and offline folders worked just fine. But recently I installed SP2 on Win2k and did a samba upgrade to 2.2.3 and now the offline folders do not work any more. Everything is fine until I go offline, */CSC/ contains my offline files and everything seems fine, but when being offline I always get access denied m...

Hi All, I've been running a Samba 3.4.0 on Ubuntu 9.10 for over a year at a friend's office and it has been extremely stable. But I've suddenly hit a scenario where Windows 7 clients can no longer properly sync the main share as 'Offline Files' I found it highly unreliable under Vista Business, then Win7Pro seemed to work much better; but suddenly I am finding that the sync is succeeding but the files are not actually available offline. Here are the scenarios I am seeing: 1) A user updates an offline copy of an Open Offic...

...support for Intel64 before. It had only a function to log the MCA error data received from hypervisor. http://lists.xensource.com/archives/html/xen-devel/2008-09/msg00876.html I attach patches that support not only error logging but also Page Offlining function. The page where an MCA occurs will offline and not reuse. A new flag ''PGC_reserved'' was added in page count_info to mark the impacted page. I know that it is better to implement the page offlining for general purpose, but I implemented for MCA specialized in this first step. And I also implement the MCA handler of Dom0 w...
